Blanc said: "When I was a player my philosophy was always to play an attractive style. Even though I was a defender, I liked to play the ball whenever I could.
"I was lucky enough to work with some coaches who advocated that same style, especially Sir Alex. When you are Manchester United, you have the players to play like that. It is easier for him than others because of the players he can call on.
"I am in contact with him a lot. We tell each other about our teams and talk about English and French players. His knowledge of players in France always astonishes me.
"For me it is a question of principle. I want my team to play with the same philosophy as me."
