The former striker insists that the ex-midfielder has made the Italian giants great again
Andriy Shevchenko has praised former AC Milan team-mate Gennaro Gattuso for turning around the Rossoneri's fortunes since replacing Vincenzo Montella.
Milan were failing to reach their potential earlier in the campaign after plenty of pre-season investment, the club bringing in the likes of Leonardo Bonucci, Hakan Calhanoglu and Andre Silva.
Montella was sacked in November with Gattuso stepping up from the youth team to lead the fallen giants.
It took him a while to get some consistency in Milan's displays, but since the turn of the year they have been one of the form teams in Serie A and are closing in on a European place.
