There is a difference between dribbling/skill and technique, I see loads of African players who can dribble the ball well or show skills.
Ignore the whole 'African' thing, this is true for many physical/fast players as opposed to slower/weaker players, players play on what they are good at. A slow player has to be good technically. A fast player doesn't have to particularly, up to a certain level.
When you combine both you get fantastic players, the likes of Yaya, Eto'o and Essien are exactly that.
