I'd say:
-
Messi
-
Ronaldo
-
Suarez
-
Neuer
-
Neymar
-
Ibrahimovic
-
Gareth Bale
-
Iniesta
-
Di Maria
-
Robben
edit: format
edit 2: Some have made points for some players being put in and others out. I feel Bale will be remembered for the transfer record. Di Maria will be remembered for his transfer from a Champions League winning club to Manchester United imho, although a case could be made for Xavi or Lahm to replace. I won't be changing the original list though. Tl;dr - I like my list.
