London – Theo Walcott will miss Arsenal's Champions League match against Montpellier at the Emirates Stadium on Wednesday with a shoulder injury, manager Arsene Wenger said Tuesday.

Walcott suffered the injury during Arsenal's 5-2 North London derby win over Tottenham Hotspur in the Premier League in Saturday, but did play on and scored the Gunners' fifth goal in added-on time at the end of the match.

He is now due to undergo a scan although Wenger said Tuesday he expected Walcott to be sidelined for only a brief spell. – Sapa-AFP
