Really good point, but I can't see Sarmiento being part of that rotation.He does a lot right. He’s young. Full of potential etc etc etc, I don’t have a great deal of criticism for him, he will improve and improve, no doubt, but in my ignorance, I suggest he can and will get stronger, steadier on his feet and be able to ride challenges better…he also needs to improve his decision making, look up and around him more, have better positional awareness of his team mates and an available pass and not try to do too much on his own. Typical criticism of a young player, keen to do well and impress, no bad thing by any means, but his efforts need to be more focussed towards a team effort. He often does SO MUCH right and yet tries to go just that bit too far and do that bit too much when he can utilise his team mates more. IMO. (Equally true of Enciso too perhaps?)
What the hell do I know, but a healthy, considered rotation of Enciso/Buonanotte/Sarmiento seems to me to be in both the players and the clubs best interests. They each would’ve got more than enough (and not too much) game time last season if they’d all been fit etc, and I strongly suspect, even without Europe, it’d be the same this season coming.
I saw quite an interesting predicted set up online somewhere where they seemed to think that we'll play with 3 CMs. Weiffer and Baleba (with one playing a hybrid CDM/CB), and a more attacking technical midfielder that they thought was likely to be Enciso (maybe as you say, backed up by Facu, with maybe Gilmour/Dahoud or Moran as the other option depending on transfers).
