AC Milan legend Gattuso: I'm now Allegri fan
The midfielder had been one of the tactician's harshest critics when walking away from San Siro in the summer for a new career with Swiss club Sion.
"I changed my mind on Allegri," Gattuso told Milan Channel.
"He is the only person who can lead this Milan. He took control of the locker room precisely because he has the ability to let everything slide off him."
