Former AC Milan goalkeeper Christian Abbiati admits he's a fan of Mike Maignan.

Abbiati rates Maignan as good as any goalkeeper in the world.

He told La Gazzetta dello Sport: "He plays alongside (Thibaut) Courtois.

"He amazed me, yes, but only because I didn't know him. My pupil however, even if many will turn up their noses, is always Gigio (Donnarumma). For me he is a force of nature, then it is obvious that mistakes are made.

"But he is still so young."
