AC Milan have announced the departure of boss Vincenzo Montella after Sunday's 0-0 draw with Torino.
Gattuso, a former midfield general at San Siro, will step up from managing the club's youth side, who have lost just once in their previous five outings.
However Montella failed to live up to those expectations and the club now sit in seventh, 18 points behind league leaders Napoli.More news: Meyer calling for "all-out investigation" after JT Barrett injury

Gattuso went on to have short spells at Palermo and Greek outfit OFA Crete, while he also guided Pisa to Serie B - and then went on to see them finish bottom - before going on to take the U19 job at Milan. "A press conference is scheduled for tomorrow to present the new coach at Milanello training centre".
"I thank the fans for their support, [managing director Marco] Fassone and [sporting director Massimiliano] Mirabelli for this opportunity and my staff for supporting me throughout".
"I hope Rino takes Milan back where they belong".
That is followed by a home game with Bologna and a trip to Hellas Verona before they host Atalanta on December 23 and end the year at Fiorentina.
Milan lanuguish in seventh place, 11 points away from the fourth position which would guarantee a place in the Champions League next season.
