Gattuso has played under Ancelotti for eight trophy-packed seasons at A C Milan and he is convinced Ancelotti will have no trouble adapting to the Premier League.
"If there are any attitudes that do not fit in with his way of thinking at Chelsea, they will learn very quickly they need to change that attitude. In England, Alex Ferguson is famous for his treatment in the dressing room when things are not as he wants, and the same is true with Carlo. When he is not happy, you will know about it," The Sun quoted Gattuso, as saying.
"He does not act that way to try to be a big man or because he likes the sound of his own voice. He does it because he knows it is for the good of the team," he added.
"Ferguson and Carlo are two of the most successful managers in the world, so it proves their methods are right. With Carlo, the players are under no doubt who is boss," Gattuso said.
