Santiago Mário dos Santos Mourinho is a Portuguese former professional football manager. Mourinho is one of the most successful coaches in the history of football.

Mourinho began his professional managerial career with Benfica, following in the footsteps of his father, legendary football manager José Mourinho and becoming the youngest manager in the history of the Portuguese League at the age of 28.

Throughout his career, Santiago has managed some of the biggest clubs in the world and boasts an incredible 43 competition wins. The highlight of his career came during his time as manager of Paris Saint-Germain, where in the 2025/26 season he led the club to seven trophies including the Champions League title, Santiago's second with the club.

Santiago is the second child and only son of legendary football manager José Mourinho. To date, the father-son manager duo have only managed against each other on one occasion on 19 May 2024. Lazio (managed by José) were beaten 1–5 by Santiago's title winning Roma side, although Santiago did not celebrate any of the goals.

Early life and education
Mourinho was born in 1990 in Porto while his father was training as a coach in the city. He had an unsettled childhood due to his fathers work and the need to move city and country frequently. He has since claimed that he felt most settled while living in Barcelona as his father worked as assistant manager alongside the likes of Bobby Robson and Louis Van Gaal.

This meant that Mourinho never really settled into schooling and never felt a connection to this, instead turning his attention to football.

Early coaching career
In early 2016, Mourinho joined Lille as a youth coach, which is where he met up with his future assistant manager, João Sacramento. Later that year while manager of Manchester United, José Mourinho added Santiago to his coaching setup. Santiago departed Manchester United ahead of the 2017/18 season to join Juventus as a first team coach under manager Massimiliano Allegri. During his time under Allegri, Mourinho was often praised by the Italian manager for his foresight and awareness of tactical developments he felt Juventus needed to make. He departed at the conclusion of the season to pursue his managerial career.

Benfica
Mourinho was confirmed as Benfica manager on 16 July 2018, becoming the youngest manager in the club's history. He was unveiled in front of the Benfica fans the following day. He then won his first game in charge of Benfica on 8 August, a 1-0 home win in a Champions League qualifier game against Slavia Prague. His first league game came on 18 August which resulted in a 1-1 home draw against S.C. Braga.

Mourinho was sacked by Benfica on 16 December that year, following disappointing results and a run which saw the team win only 3 of their last 11 games. Mourinho found out that he had been relieved of his duties only a couple of hours after a 0-1 home defeat to Santa Clara

Sporting Lisbon
Mourinho was confirmed as the new manager of Benfica's rivals, Sporting Lisbon on 3 June 2019. Mourinho's first game in charge of Sporting resulted in a 4-0 home win against Djurgårdens followed by a 3-0 home win against F.C. Paços de Ferreira. Sporting under Mourinho enjoyed an excellent start to the season, remaining unbeaten for 20 matches from the start of the season until a 1-2 home loss against Gil Vicente. They also managed to finish top of their Europa League group, moving on to the knockout stages. Mourinho was praised for being able to get the best out of Portuguese midfielder Bruno Fernandes who shined in the Mourinho system.

In the latter half of the season, Mourinho guided Sporting to the final of the Europa League, knocking out St. Gallen, Schalke, Lazio and Chelsea along the way. He also led the team to the final of the Taça de Portugal having knocked out strong favourites F.C. Porto along the way. The League title was confirmed after a 0-2 away win against Gil Vicente, just 4 days before the Europa League final against Tottenham. Sporting won the match 4-2, with Mourinho becoming the youngest ever winning manager of a UEFA competition at just 30 years-old. 4 days later, Sporting completed the treble after defeating Leixões 3-0 to win the Taça de Portugal title.

Sporting confirmed that they had agreed to part ways with Mourinho on the 28 May.

Chelsea
Following speculation over his future, Mourinho was officially announced as the new manager of Chelsea on 6 June 2020, replacing the departing Jorge Jesus. The arrival of Santiago in England was hailed by the British media as the arrival of the "Special Son" - in reference to his father, José's nickname of "The Special One" when he first came to England.

Santiago's Chelsea team started the season terribly, losing on the opening weekend of the season 4-0 against Manchester United at Old Trafford. They then went winless in their next 5 games. Chelsea's first win of the season came in the Europa League against FC Midtjylland. They followed this up with a 4-0 home win against Newcastle United.

However, following their poor results and inconsistent performances during the season, Santiago was sacked as Chelsea manager on 4 April 2021. Chelsea were in 8th position in the Premier League at the time and were still in the quarter finals of the Europa League, which they would go on to win without Mourinho.

Roma
Mourinho was appointed as the new Roma manager on 7 June 2021 on a 3-year deal. The next month Mourinho sanctioned the transfer of club captain and star player Lorenzo Pellegrini to Tottenham. The transfer was £88million - a record fee for an Italian player and the most ever received for a Roma player. The transfer met backlash from much of the fanbase due to Pellegrini's popularity and ability on the pitch. Defender Alessandro Florenzi was promoted to captain ahead of the 2021/22 season.

2021-2023: Returning Roma to the Champions League

On 19 May, Santiago and his father José faced each other for the first time on the touchline when Roma faced Lazio in a Serie A match. The result was a 1-5 away win for Santiago's Roma, although he did not celebrate any of the goals.

Following the team's league win, there was much expectation for Mourinho to sign a new contract and remain with Roma. However, on 30 May 2024, Roma announced that Mourinho would not be remaining with the club for the following season. when later commenting on his reasons for leaving Roma, Mourinho said: "it had become clear that myself and the board had different aspirations for where we could take the club".

The 2025/26 Champions League final took place on 30 May at the Signal Iduna Park in Germany between Mourinho's PSG and Premier League champions Man City. Man City opened the scoring with a tidy finish from winger Raheem Sterling in the 5th minute. PSG quickly answered back with an 11th minute strike from outside the box by Milinkovic-Savic to bring the game back level. In the 81st minute Milinkovic-Savic once again shot from outside the box, with the deflection coming off Man City's Christoph Bahr sending the ball into the net. The goal went down as an own-goal and helped PSG to win the match 2-1 and secure their 7th trophy of the season. This being the first time in the history of football that a single club side had won 7 trophies in a season, an historic septuple.

Following this success, PSG announced that Santiago had decided to vacate his role as head coach of the club. When asked about his reasons for leaving, Santiago said:

"there was nothing more to be done, I won everything, and so I need a new challenge. I'm not one of these managers who will sit at a club collecting easy trophies to create the perception of greatness. This is not greatness."

2026/27 Season: Premier League title
Santiago Mourinho was approached by Manchester United following his resignation at PSG. He was appointed the new Man United manager on 21 June 2026. This was the third time Santiago managed the same club as his father; the other two clubs being Benfica and Chelsea.

Upon his appointment, Santiago made Jude Bellingham his number 1 transfer target and publicly called on both the player and club to act on this. The signing of Bellingham was confirmed on 31 July from Bayern Munich for a club record fee of £150million, also a record for an English player. The signing of Bellingham meant that 3 of the 5 widely considered to be best players in the world at the time all played for Man United. The other two being Erling Haaland and Kylian Mbappe.

2027/28 Season: Decline in results and sacking
During the summer transfer window, Kylian Mbappe moved to Real Madrid for a record-equalling fee of €222 million (£200 million). The move sparked controversy as Mourinho publicly questioned the move and claimed that he didn't sanction his departure.

The new season started with a win in their first game, a 1-0 victory over Wolverhampton Wanderers F.C. in the Community Shield.

However, the season was clouded with poor results along with an ongoing dispute between Santiago and star player Erling Haaland. This ultimately led to Haaland joining PSG the January transfer window in a swap-deal which saw Mourinho's former player Pellegri move to Old Trafford.

Despite this change in personnel, it wasn't enough for Mourinho to turn around his Man United fortunes, and he was ultimately sacked by the club following a 4-2 defeat to West Ham which left the club sitting in 8th in the league.

Inter went on to lift Serie A only losing 3 games and conceding 15 league goals all season. This being the first Serie A title for the club since the 2009/10 season, 20 years prior. The Inter manager during this last league title was Santiago's father, José Mourinho.

The title win was helped by the additions of Inter youth players coming into the Inter team.

2030/31 season: Second league title win

On 1st February, Santiago's long-serving assistant manager, João Sacramento departed from his role in pursuit of his own managerial career, joining Girona. Subsequently, Davide Ancelotti was appointed his replacement becoming Santiago's new assistant.

Tactics
Santiago Mourinho is noted for his tactical prowess along with his ability to adapt his tactics depending on different situations. An example of this adaptability could be seen during Mourinho's time with Roma where he employed a solid, defense-minded 4-4-2 formation. This tactic worked to strengthen the Roma defense, along with getting the best out of Roma's two strikers at the time, Edin Džeko and Divock Origi. However, Mourinho was able to adapt his tactics towards the end of his time with Roma after both strikers were no longer viable options, by changing to a 4-1-4-1 counter-attacking tactic. This managed to get the best out of the talented midfielders Roma signed during Mourinho's tenure such as Bruno Fernandes, Enzo Fernandez and Arthur Melo. Changing to a sole striker also suited the changing situation of the squad with Dusan Vlahovic becoming the main striker. This tactic worked by allowing the team to remain defensively solid, but gave them a deadly edge when attacking, allowing them to win Serie A with this tactic.

Another example of Mourinho's tactical awareness is the contrast between his defensive Roma tactics and his more attacking PSG tactics. Mourinho changed to a 4-2-3-1 high-pressing tactic upon arriving at PSG and saw immediate success with this. This allowed him to get the best out of PSG's many attacking wingers and midfielders and allowed PSG to score at will. However, this high-pressing tactic also worked defensively as PSG only conceded 3 goals in their first 26 games, a new record for clean sheets and goals conceded.

Santiago Mourinho has drawn comparisons to his father, José for some of the pragmatic tactics employed at various times during his career. However, Santiago's record of also changing to more attack-minded tactics when he feels necessary is in contrast to José Mourinho. His positive 4-2-3-1 tactics employed at PSG are comparable to those used by both Jürgen Klopp and Mauricio Pochettino. This puts Santiago in a unique bracket for a manager where few managers before have been known to so drastically alter their tactics throughout their career, most notably of which being Sir Alex Ferguson.

Reception
Santiago Mourinho first gained notoriety due to his high-profile father, José Mourinho. However, he then went on to build his own footballing legacy and went on to be considered to be one of the most talented managers in the world. He was seen as a new generation of manager who was able to adapt to different situations and get the best out of his players. His image of being the future of football managers is supported by his habit of seeking out talented young coaches to join his coaching staff, such as his long-serving assistant manager, João Sacramento.

Santiago is frequently spoken about in the conversation of best football managers in the world due to his incredible win record with most of the clubs he has managed, along with his impressive trophy haul which includes 4 Champions League and 14 domestic League titles.
