The Rossoneri have turned to a San Siro favourite after sacking Vincenzo Montella - but there are doubts over the 39-year-old's coaching credentials
The first time a teenage Gennaro Gattuso saw Andrea Pirlo in action, he was left feeling so insecure about his own abilities that he considered quitting football.
Luckily Gattuso persevered and he went on to enjoy a wonderfully successful career playing alongside Pirlo, for both Italy and AC Milan.
He was the perfect foil for the playmaker, a snarling beast of a midfielder whose primary purpose was to break up opposition attacks, reclaiming possession in order to get the ball back to Pirlo as promptly as possible.
