Lucas Perez ruled out of Arsenal's Champions League

Lucas Perez has been ruled out of Arsenal's Champions League clash with Bayern Munich.

The Spaniard missed training on Tuesday due to a hamstring problem.

He made a brief cameo in the win over Hull but will play no part in Munich.

Perez didn't travel with the rest of the Gunners squad.

Aaron Ramsey remains out with a calf injury while Santi Cazorla is still sidelined.

Granit Xhaka is back in the frame for the visitors though after a domestic suspension.

Bayern have been boosted by the return to training of Xabi Alonso.

The Spaniard limped out of action on Monday but completed Tuesday's session and is now expected to be fit.

Jerome Boateng and Franck Ribery are sidelined for the hosts, though.
