He is so technically good he could adapt to any style of play so there would be no worry about that.
He would have to buy into Peps ethos regarding work rate off the ball
The only other question would be is he the right sort of character to fit the dressing room....we all know how important this is to Pep and the club...he needs to be humble as Pep has said many times - if he is then its a no brainer
however the real stumbling blocks would be his desire to leave madrid - this idea that Madrid/Barca are the pinacle of world football is the next thing we need to break (we have made a start on this already very recently!) but its going to take a while to get rid of the tired old line that the media drop in to all articles about players ultimately wanting to go to Barca/Madrid
the price (could we realistically pay what Madrid would ask)?
Im also sure Madrid wouldnt want to sell to us - the political pressure applied would be huge.
Love it to happen but cant see it
