This year, the team has relied too much on some older players. New blood is needed for next season, which will be a transition year.
I don't think Iniesta has a significant role to play after this season. It seems wrong to ask him to play a smaller role with this team, so it would be best if he moves on, so he can cash in for one more big contract in a lessor league.
Busquets, well, he just is not fast enough these days. I don't know if he would be better playing fewer minutes, but he can no longer be automatic in the first 11.
Of course, the minutes played this year by Rakitic, Messi and Suarez have been way too much. I don't blame Valverde for this, the alternatives to these three have certainly proven that they are just not good enough. Griezman would provide the depth needed up front.
In midfield, I do hope that Coutinho, Dembele and S. Roberto can hold down bigger roles next year. I think they will. But Barca still needs to add at least one more top-level midfielder. I don't know whom, but no one tiny or unable to play excellent defense, please.
If S. Roberto plays a lot in midfield next season, more depth is needed at RB. For depth on the back line, I would keep Verm and Digne. Let Mina go somewhere where he can get on the field. Bring in someone who can cover both RB and CB. Go with 3 CBs and 2 combo CB/FBs.
