Yeah, its a list of the best players in different positions from past games.
I put Babangida in because although he is technically not as good as Rivaldo or Beckham, he can be extremely effective in his position. With his pace, short height, dribbling and balance he is by far the most effective dribbler at pace down the wings.
Becks excels at set pieces and passes obviously, but is a bit sluggish. I think everyone's opinion will depend a lot on their style of play. I don't have a very good success rate with crosses, and rely more on passing, one-twos, chipped passes and dribbling to score.
