Theo Walcott will miss Arsenal's Champions League fixture against Montpellier tomorrow night with a shoulder problem.

The England international, who scored during Saturday's 5-2 win over rivals Tottenham Hotspur, is believed to have sustained the complaint during a recent training session.

He will be joined on the sidelines by Brazilian full-back Andre Santos.

However, Arsene Wenger will have Kieran Gibbs and Gervinho available for selection again following injuries.

Arsenal are currently second in their group with two matches remaining.
