Without adding more fuel to the fire regarding Donnarumma's contract talks (which we won't know more about until later today), it's worth mentioning that Real Madrid and Manchester United are ready to pounce for Milan's wonderkid if today's negotiations fail.
Fassone says "it is a definitive decision" and "it saddens us" but that "Milan will move forward". The player evaluated it, taking into account factors not only economic, but also technical and personal factors.
"This decision, taken by the player and his agent, makes us sad but we must move forward, Milan must move forward".
With his current contract at San Siro due to expire after the 2017-18 season that leaves Milan in the tough position of either losing their prize asset for nothing or selling him during the transfer window.
Donnarumma became the second-youngest goalkeeper to play in Serie A when he made his Milan debut as a 16-year-old in 2015.
The teenage prodigy has emerged as one of Europe's hottest goalkeeping prospects, but there has been continued doubts over his future with agent Mino Raiola flying in to Milan ahead of a deadline for him to commit his future.
And it appears Real Madrid have already made a march over their rivals to land his signature.
Goal reported on Thursday morning that Donnarumma was set for a decisive day of talks involving Raiola and Milan negotiator Massimiliano Mirabelli.
