Definately Yaya for me, the thing is he has actually played in these different positions and at a high level. Don't think the likes of Ronaldo or Rooney could play at CB in a Champs League final. So all round player Yaya with probably Busquets going close.

But best player....Messi by a mile.

Yaya.
Schweinsteiger.
J Martinez

All ridiculously versatile.

Paul Lake.

Yaya is 2nd only to Messi (and maybe Glauber Berti)

I'd have to say Berti

Hang on, I forgot - it's got to be Alan !! (with Berti as a close second)

My mate Dave from the dog and duck.
Not been discovered yet but after 6 pints and a pack of 20 he can play anywhere on the pitch

It used to be Gerrard. In his prime he could do everything

But still Zambia did, didn't they?

Yaya is definitely up there. So is Kompany to be fair, could do a job in CDM & CM. Overall I would say Yaya, Schewieinsteger (?), Ronaldo, Rooney, (still overrated tho) & Xabi Alonso are definitely the top all round players. Oh and Essien if he can get back to the player he was before his injury. Lucio too.
