AC Milan's midfield duo of Gennaro Gattuso and Alberto Aquilani has been ruled out of Sunday's derby with Inter Milan.

Gattuso has been diagnosed with an eye disease called ocular myasthenia, which he picked up while on the club's recent trip to Dubai, while Aquilani is set to miss the next month because of an ankle injury.

Aquilani has tallied one goal in 15 Serie A matches this season, while Gattuso has started only one game and his return to action has yet to be determined.

Milan enters the derby eight points clear of Inter, which resides in fifth place.
