I play FC Barcelona so this should be valid advice. I play a 4-3-3 formation with two BTB, usually rotating Willian, Song, Busquets and Özil. Busquets is usually the best of all them, and Willian has a tendency to try long shots far too often to my liking.
As a decent GK backup you can get Branescu, Guilherme or Ospina, they should do nice.
