Considering his age that is not young anymore, 23 goals is a good achievement at least. But you are right, if he can only score 23 more or less yes there is a possibility other strikers can handle it. By the way, at the moment I haven't seen any good move at the Barcelona club, in my opinion they should release of their players two or three players. Because previously their funds from the advantage transfer of Antoine Griezmann and Trincão, maybe already used to sign Vitor Roque, also to improve their finances little by little Barcelona must be ready to sell their players again.
To balance their expenses of course barcelona will sell their players in this transfer window. There are even 5 players who will soon be sold by Barcelona to other teams in this transfer window. I saw Kessi before he was a key player in the Ac milan team but when he went to Barcelona he seemed to find such a big setback against his form that xavi wanted to let him go in this transfer window.
For that we are going to these five players that will be sold by Barcelona. Will barcelona sell him at a cheap price considering that not too many teams are interested enough to get players that barcelona will sell. like Dest he seems to fade away and will find it difficult to find a new club for his next career. I think Barcelona will do a lot of things and they will often terminate contracts if that is the last step for them.
