Rome: AC Milan striker Zlatan Ibrahimovic has been ruled out of the European Champions League football game against Barcelona after he picked an injury during training Monday.

The Swede picked up a muscle problem in training earlier Monday and will miss the Champions League showdown with his former club Tuesday, a newspaper reported. 

The former Inter and Juventus forward is now also a doubt for the Italian Serie A game at the weekend against Napoli. 

The loss of Ibra will give boss Massimiliano Allegri some selection problems as he has now just two fit strikers in the squad. 

With Robinho also sidelined due to injury and Pippo Inzaghi excluded from the Champions League squad, the Rossoneri have just Antonio Cassano and Alexandre Pato available for selection.
