apotheosis
O'Fortuna
Personally, I don't think Sneijder would be any more incapable of playing CM than Giggs is, and we have used Giggs there a good bit this season.
It's not a question of him being incapable, it is more a question of whether he is the best choice for playing alongside Carrick in a central 2.
Imo no. I believe Banega, Schweinsteiger or Sahin would be better suited to playing deeper. Sneijder imo is most effective playing as the most advanced player in a midfield 3 and would not offer as much defensively as the others i have mentioned.
If we want to play 4-5-1 then Sneijder's the man. But in a 4-4-2 i believe there are other less expensive options who would better fit the requirements of our current system.
