Robinho admits he has found his best form again at AC Milan.
He said: "I like Allegri, as with him you play real football, the kind that I like. We play with the ball to feet, spreading the play down vertical lines quickly.
"Among all the Coaches I have worked with, I'd say Allegri is the best when it comes to the concept of football.
"In terms of my growth as a player, Fabio Capello was very important at Real Madrid. He's a real sergeant with a fist of iron and has no favourites, talking to everyone the same way."
