DM - Lars bender, Capoue and Chedjou
LB RB CM LW RW ST
LB - Bengué or Alaba
RB - you already have one of the best in the game... and it's quite difficult to find anyone much better than Rafael. Maybe... Debuchy?
CM - Fellaini or Cabaye
LW - Florenzi, Simone Pepe, Di Natale( for 2 seasons... than he just gets old...)
RW - Belhanda... although I'm a fan of Valencia
ST - Van Persie, Rooney for more complete players, Chicharito is still a machine... but if you want other players I'd go for Destro, Neymar and Damião.
