Inter Milan great Walter Zenga says Mike Maignan's injury absence is hurting AC Milan.

The champions haven't been able to count on their French goalkeeper consistently this season.

Zenga told Sky Italia: "We expect to understand how the teams have faced the break. Not so much from a physical point of view, but how will the various players manage to hang up the plug and keep the concentration high for a long period after two months of stopping.

"In Milan the absence of Maignan affects a lot, he has been the top player of the Rossoneri and has always been decisive in important situations. Losing Maignan for Milan is a big negative.

"Antonio Mirante and Ciprian Tatarusanu are dated, together they are 80 years old."

Milan announced the signing of Colombian goalkeeper Devis Vasquez from FC Guarani yesterday.
