AC Milan vice-president Adriano Galliani says M'Baye Niang cannot leave the club this summer.
Newcastle United were hoping to bring the 18-year old attacker in on a season-long loan but Galliani has made it clear that any such deal will not occur as the Rossoneri need him at the San Siro.
"He can't leave," he said.
"We've got Robinho and [Giampaolo] Pazzini both out and, until the Champions League play-offs are over, he can't leave."
