The Italian striker rejoined the Rossoneri on a season-long loan deal late last month from Premier League giants Liverpool following a disappointing debut season on Merseyside, where he managed to find the back of the net just once in 16 league appearances.
His future at the club was thrown into doubt after manager Brendan Rodgers signed the likes of Christian Benteke, Roberto Firmino and Danny Ings, and his return to Serie A is likely to be his last chance at fulfilling his potential at a top European club.
Upon his return to the San Siro, there has been a behaviour clause inserted in his contract and Galliani says he has noted a drastic change in the 25-year-old:
“He has an extraordinary attitude, he’s changed radically,” Galliani said.
“He’s the first to arrive at [the training centre] and the last to leave.”
“Coach Sinisa Mihajlovic often wants the players to have breakfast at 8.30am and he’s always there before eight.”
“He’s probably realised that this is his last chance and I’m sure he won’t waste it. His technical ability has never been in question. If he continues with the approach he’s had in this first week then he’ll be fine,” Galliani added.
