AC Milan are not willing to let Andre Silva leave the club in January, coach Gennaro Gattuso insists.
Silva earned a reported €38million move to Milan after impressing in his maiden full season in Porto's first team, scoring 21 goals in 43 appearances in all competitions.
"Andre Silva is in good shape, he has this incredible desire to work hard. The biggest responsibility is mine, to be more courageous in throwing him into the mix," said the Milan boss at a media conference ahead of Sunday's match against Cagliari.
"He is young and needs to improve some things, but it's no coincidence so many clubs want him. Milan moved well to sign this player and want to keep him."
Gattuso also has no intention of letting Manuel Locatelli leave San Siro.
He said: "Locatelli came to talk to me and the club a week before the mid-season break. He has to stay here.
"He has to understand the 'mezzala' role a bit better. He can do it because of his physical and technical qualities. It's right that he remains here."
Gattuso's own future continues to be a subject of debate, but he was uninterested in responding to a Tuttosport report which alleged Milan were lining up Napoli boss Maurizio Sarri to take over next season.
"[My future] is not the priority. Time will tell but I just have to work calmly," he said. "I must do my all, try to win every game.
"The last problem Milan have to worry about is Rino Gattuso. I feel at home here and have great responsibility towards this club. Those aren't just words, I really mean it."
