Gianluigi Donnarumma will not commit to a new contract at AC Milan until the success of the club's takeover has been assessed, his agent Mino Raiola says.

The 17-year-old goalkeeping sensation is only contracted to Milan until 2018 and has been linked with many of Europe's biggest clubs, including Chelsea, Juventus and Manchester City.

Chinese company Sino-Europe Sports are set to take over the San Siro side after signing a preliminary agreement in August, but the success of that move and direction of the club are important factors for Donnarumma before he makes a decision.

"We will have to see what will become of this Milan before we make our assessments," Raiola told TuttoMercatoWeb.

Donnarumma's AC Milan team-mate Ignazio Abate, though, is very confident the shot stopper will opt to remain with the club.

"Honestly, I'm calm," the defender told Premium Sport.

"The lad has always been a Milan fan, as he said, and he's already at a top club. 

"This club will come back to the top of world football sooner or later, and he will definitely stay and be a star in these colours."

Donnarumma has been Milan's first-choice goalkeeper since breaking in to the team in October 2015.
