Guille Fernández

Guillermo "Guille" Fernández Casino (born 18 June 2008) is a Spanish footballer who plays as a midfielder for Barcelona.

Club career
Born in Rubí, Barcelona, Fernández and Toni Fernández began their career at Espanyol, before making the switch to Barcelona in 2018. In March 2022, following impressive performances for the club's Infantil A squad, he was promoted to the Cadet B team - playing with players a year older than himself - and marked his second appearance with a goal. The following year, in August 2023, he was included in Barcelona's under-18 squad, despite only being fifteen, for their pre-season preparation. He was given his debut in the UEFA Youth League by youth team manager Óscar López in September, becoming Barcelona's second-youngest player in the competition, behind Lamine Yamal. Continuing his meteoric rise at Barcelona, Fernández was included in the first-team squad's training for the first time in October 2023, alongside fellow youth players Pau Cubarsí, Marc Guiu and Áron Yaakobishvili, due to the absence of a number of first-team players.

International career
Fernández has represented Spain at under-15 level.

Personal life
Fernández' cousin is fellow Barcelona player Toni Fernández, the pair's fathers are brothers and their mothers are sisters.
