Double blow for Gunners

Arsenal will be without defender Thomas Vermaelen (achilles) and midfielder Abou Diaby (ankle) for their Champions League Group H opener at home to Portuguese club Braga on Wednesday.
But winger Samir Nasri has recovered from knee surgery, while full-backs Gael Clichy and Bacary Sagna are expected to return after being rested for the English Premier League win over Bolton.
Theo Walcott, Robin van Persie (both ankle), Nicklas Bendtner (groin) and Aaron Ramsey (leg) remain out of contention.
