AC Milan vice-president Adriano Galliani admits Stephan El Shaarawy is a doubt for their Champions League clash with Barcelona.

The young striker is struggling with a knee injury.

"We hope that El Shaarawy can recover in time for the match. It is fortunate we signed Mario Balotelli in January, as Giampaolo Pazzini has been injured and El Shaarawy is trying to recover from a knee inflammation."
