2019–20 Derby County F.C. season

The 2019–20 season was Derby County's twelfth consecutive season in the Championship in their 136th year in existence. Along with competing in the Championship, the club also participated in the FA Cup and the EFL Cup. The season covered the period from 1 July 2019 to 22 July 2020.

This season was the first for manager Phillip Cocu, after the previous manager Frank Lampard left on 4 July 2019 to become head coach at Premier League club Chelsea.

After a poor first half of the season saw Derby in 17th and just seven points clear of relegation, the arrival of Wayne Rooney saw a galvanised Derby side lose just three of their sixteen games after the New Year and just three points off the playoff positions with just five games remaining. However a run of four straight defeats - all against teams occupying the top six - ended any hopes of a third consecutive playoff campaign as they finished six points behind Swansea City in 6th. The 10th-placed finish, and a return of 64 points, was Derby's worst league performance since the 2012–13 season, when they also finished 10th but achieved just 61 points.

Pre-season
The Derby squad reported back for pre-season training on 1 July, with uncertainty remaining over the future over Frank Lampard, who was excused from attending training to undergo talks with Chelsea about their vacant managerial position. With speculation over Lampard's future, Phillip Cocu was installed as favourite to replace Lampard, with former Ram Darren Moore, Lincoln City's Darren Cowley, Derby Academy boss Darren Wassall, Chris Hughton and Wycombe Wanderers manager Gareth Ainsworth also rumoured. Lampard was officially appointed as Chelsea's head coach on 4 July, after just one year at Derby and Phillip Cocu was confirmed as his replacement the next day, becoming the first foreign manager in the club's 136-year history. Following Cocu's arrival, and with the new season just a month away, Derby were given promotion odds of 11/2, putting them as ninth-favourite.

Pre-season preparations began with a 10-day training camp at the IMG Academy in Bradenton, Florida. A 2–0 victory over local USL League Two side Sarasota Metropolis was followed by a match with fellow EFL Championship side Bristol City, which was abandoned at half-time due to extreme weather conditions, with the Rams trailing 1–0. The match was rearranged for the following day and played over two, 30-minute halves, with the Derby winning 2–0. Derby returned to England to round off their pre-season preparations with a 5–2 victory at Burton Albion in the Bass Vase, and 1–0 defeats to Segunda División side Girona and Scottish Premiership side Glasgow Rangers.

Following their failure to gain promotion the previous campaign, Derby set about reshaping the squad with three first team players, former club-record signing Bradley Johnson, Nick Blackman and Jacob Butterfield, leaving the club to join Blackburn Rovers, Maccabi Tel Aviv. and Luton Town respectively. Three players joined the club, Everton midfielder Kieran Dowell and Brighton & Hove Albion defender Matthew Clarke on season-long loans, with the sole permanent signing being Arsenal's Krystian Bielik for a potential club-record fee.

August
Derby started the season with a 2–1 victory away to recently relegated Huddersfield Town, with the result itself coming against a backdrop of rumours that Manchester United and England all-time leading scorer Wayne Rooney was on his way to the club on a player-coach deal. The deal was confirmed the following day, with Rooney signing a deal which would see him join the club following the end of the MLS season on a £100k-a-week deal, which would be partly subsidised by club-sponsor 32Red. The end of the transfer window on 8 August saw Derby sign Huddersfield Town goalkeeper Ben Hamer and Bristol City's Jamie Paterson on loan, with Scott Carson leaving on loan for Manchester City.
