VdV? He was technically very good and had skill, but wouldnt say his actual dribbling skills was all that...
Good call. I don't remember him ever beating a player with the ball at his feet and he certainly wasn't quick. Mata is another good example - neither really a dribbler or a quick player.
You could probably also count Paul Scholes who played as the advanced midfielder for Man Utd on many occasions (although that was more in the 4-4-2 days - but still same sort of role.
Carzola at Arsenal?... Doesn't seem like a player who relies on pace or dribbling?
Lampard at Chelsea? Used to play as the most attacking midfielder - very little pace, rarely even attempted a dribble but hugely successful for many years. Prior to that there was Gus Poyet - again not pacy or a dribbler, just a creative footballer with good touch, who was excellent at getting into the right areas and then taking the right option.
What about Zidane for Real Madrid? Isco now? Diego for Athletico last season? Riquelme a few years ago?
Moutinho is another one - extremely successful in that role but doesn't rely on pace or dribbling.
Michu at Swansea in his first season (before injury). No pace and not a dribbler. Shall I stop now?!?
I would say the biggest attributes required to play as the central attacking midfielder are touch, vision, positional sense, movement, bravery and confidence. pace/dribbling ability are merely a bonus. For example Aaron Lennon has both pace and dribbling ability but I think he would make an awful attacking central midfielder precisely because he lacks several of those other attributes.
