1st Row: Zidane, Maradona, don't know, Ruud Gullit, Balderamma,
2nd Row: I think this may be the Portuguese Deco or Figo (one of those may have been born in Brazil but played for Portugal), Robin Van Persie, I will guess Socrates, (as DFWGator does as well) ?? One of the Argentines or Spaniards on Man City, (I just looked up Sergio Arguero, I am thinking him, and last? I'm tempted to say Balotelli but I don't think that is right.
Perhaps the one I took for Socrates is actually Zico. The one I thought was Figo may be Xavi.
Looks like the google trick of image search can find the images. The artist seems to be Daniel Nyari. Some of his work you can identify who it is, others no. Gareth Bale and Steve Gerrard on that page. The 3rd person in the image may well be Cristiano Ronaldo but the image was possibly cropped off, I think the same image is in the link. Some more Playmakers.
Just in case anyone is curious, I was able to run this down with some help.
