However, the player is refusing to leave and has told Barça that he thinks he can stay and fight for a starting spot.— @gerardromero pic.twitter.com/C7MsC6v9fp— Barça Universal (@BarcaUniversal) August 8, 2021The story claims Braithwaite has changed his mind on the proposed transfer because he feels he can now fight for his spot in the team next season. The striker is said to have gained more confidence over his chances due to the developments that have taken place at the club in recent days.Lionel Messi's departure would've certainly played a part. The Argentine has been allowed to leave Barcelona this summer as Blaugrana can't afford to tie him to a new deal amid their financial constraints.Braithwaite doesn't feel pressured by the club to leave the club this summer.

They are believed to be working offloading a couple of other stars as well. The likes of Clement Lenglet, Samuel Umtiti, Miralem Pjanic, Sergi Roberto, Neto and Ilaix Moriba have reportedly been placed on the market.
