#3 Samuel Umtiti
Samuel Umtiti's career has stagnated in recent seasons due to a series of injuries he has suffered at the club. The Frenchman is an excellent player on his day, but Barcelona could offload him this summer, as he simply doesn't stay fit enough to be relied upon.
Clement Lenglet and Gerard Pique are the first-choice defenders at the club, while the emergence of Oscar Mingueza and Ronald Araujo has pushed him further down the pecking order.
The imminent arrival of Eric Garcia could be the final nail in Umtiti's coffin, as his Barcelona career prepares to draw to an unceremonious end. Manchester United have been credited with an interest and it remains to be seen if the Red Devils make an offer for him.
#2 Miralem Pjanic
Miralem Pjanic has endured a disastrous spell at Barcelona so far since his unexpected move to the Camp Nou last summer. The Bosnian midfielder joined the club in a swap deal that saw Arthur move to Juventus, as the Catalans let go of a younger midfielder for someone who was entering his 30s.
The move has expectably backfired, with Pjanic failing to make an impression at the club so far. Ronald Koeman doesn't seem to count on him. with Pedri and academy graduate Riqui Puig ahead of him in the pecking order.
The former Juventus midfielder is one of the players Barcelona are willing to offload this summer, but it remains to be seen if he attracts any bidders.
#1 Philippe Coutinho
Barcelona's record signing and the third most expensive player in football history, Philippe Coutinho's move to the Camp Nou has been nothing short of a disaster. Between failing to make an impression in his first season at the club and being shipped off on loan to Bayern Munich, it has always been clear that Coutinho isn't going to be successful at the club.
He showed flashes of his brilliance after joining the club but never managed to produce consistently. Coutinho's move to Barcelona has been hailed as one of the worst transfers in football history, as the Catalans paid a staggering £142 million to snap him up in 2018.
He has been linked with a move to former club Liverpool, but that ship is believed to have sailed in recent months.
