I'd sell Song and Alves and unless the replacement is a true WC #9 or Reus Alexis is an untouchable for me
Alves's freedom needs to be reduced BY THE MANAGER. He is a professional, he does what his manager tells him to do, if Tata tells him to defend more and attack less, he will do that. But the way I'm seeing, Alves is played more like a winger -- and that's a tactical move, not something Dani does on his own.
Song has been played as a back-up. He's more than that. When we face a team that plays us with pace, he can be great, because he is good at playing direct football -- in the few games that he started this season, I've seen him accelerating our play more often than Xavi. So, if we want to be more direct, Song is a keeper, not as a back-up, but as a player we can use pretty often.
Alexis has had a great season. He deserved more from Martino.
