#1 Philippe Coutinho
Philippe Coutinho was supposed to be the next big thing for Barcelona but in reality, the Brazilian hasn't made a mark of any significance in the team. One of the biggest names in world football when he signed for the Catalan club, Coutinho's situation at Barcelona has been more like that of a young player breaking through the academy. The Brazilian has been second choice to Ousmane Dembele since the start of the season, and has lost the momentum he had at the end of last season due to the Frenchman's form.
There has been lot of speculation regarding Coutinho's future, and although reports suggest that most Barcelona players still believe largely in the talents of the Brazilian, the board is open to listening for offers. Coutinho has suitors from all over Europe, most notably from the Premier League.
There are chances that Barcelona might let go of Coutinho to make way for other players, both financially and sporting-wise, and reduce their ever-increasing wage bill.
