Okay well, i'm only 16 and not a professional expert in football, I haven't seen all the players in the entire world the past 30 years so this might, and probably won't be the best team for you, but for me it would. Oh, also, all the players would be as good as they were when they were as best.
Carles Puyol Fabio Cannavaro Robert Carlos Daniel Alves
Xavi Hernandez Andrés Iniesta
Messi Samuel Eto'o Ronaldo
