#4 Riqui Puig
Since breaking into the Barcelona first team last season, when he managed 11 La Liga appearances and a handful of games in other competitions, Riqui Puig has only seen three minutes of action in the 2020-21 season.
The 21-year-old central midfielder hasn't managed to break into Ronald Koeman's team, which has led to speculation about the player's imminent departure from Camp Nou in January.
Puig, on his part, remains convinced that he could fight for his place at the club and work his way into the new manager's playing XI.
Despite Ronald Koeman wanting the player to go out on loan and gain some valuable game-time at another club, Puig is unwilling to leave.
With Miralem Pjanic comfortably ahead of the 21-year-old La Masia graduate in the pecking order, something that is unlikely to change any time soon, Puig could have a rethink and opt against continuing to warm the Barcelona bench.
#3 Junior Firpo
Junior Firpo managed 17 La Liga appearances in his debut season at Barcelona last campaign.
However, the 24-year-old left-back is yet to make an appearance in the top flight under Ronald Koeman this season. Firpo has only managed a pair of substitute appearances in Barcelona's Champions League wins over Ferencvaros and Juventus.
Barcelona need to sell a few players to be able to land two of their targets - Eric Garcia and Memphis Depay in January.
Inter Milan were linked with Firpo in the summer and could rekindle their interest in the player in January as the club require a left-back. With Firpo not in the plans of the new Barcelona manager, his departure from the club could make sense from both the club's and the player's perspective.
#2 Martin Braithwaite
Following the departure of Luis Suarez, Martin Braithwaite has inherited the iconic number nine jersey at Barcelona.
However, the 29-year-old Danish forward, who joined the Camp Nou outfit earlier this year, has struggled to make an impact at the club. Braithwaite has scored only once in 16 games in all competitions for the club.
Despite the indifferent form of Messi and the long-term injury of Fati, it is likely that Braithwaite could leave Barcelona in January as three Premier League clubs are reportedly interested in his services.
Moreover, Barcelona are apparently willing to 'listen' to offers for the player, which makes Braithwaite's Camp Nou exit a very likely proposition in the upcoming transfer window.
#1 Ousmane Dembele
Ousmane Dembele was reportedly one of several players identified as deadwood in the summer.
However, despite strong interest from Manchester United, the Frenchman opted to stay put at the club and work his way into Ronald Koeman's playing XI, something that did not enthuse the club as they hoped to use funds from his sale to land Memphis Depay.
Since arriving on a mega transfer from Borussia Dortmund in the summer of 2017, Ousmane Dembele has had a stop-start career at Barcelona and has been beset by a plethora of injuries.
Dembele, who was out of action for ten months, returned to the Barcelona fold in September but hasn't set the ground ablaze with his performances - scoring thrice in eight games in all competitions.
On the few occasions he has been fit and made the Barcelona playing XI, the Frenchman has largely been a pale shadow of the player he was at Dortmund.
With Manchester United still interested in the player's services and Arsenal also reportedly in the fray, Dembele could leave Barcelona in the upcoming transfer window.
If that happens, Barcelona could hope to recoup a part of their initial investment on Dembele as the player becomes a free agent in the summer and could leave the club for free.
