Arsenal's France international midfielder Samir Nasri will be out for action for around one month following knee surgery.

The timing of the injury comes as a real blow to manager Arsene Wenger as Nasri had been in impressive form during pre-season.
Meanwhile, Tottenham boss Harry Redknapp claimed Tuesday's 3-2 loss to Young Boys in the first leg of a Champions League play-off was a 'great defeat'.

But Sebastian Bassong's header just before the interval and Roman Pavlyuchenko's stunning drive in the closing stages kept the tie alive ahead of the return leg at White Hart Lane.
"It was a great defeat - if there's such a thing," said Redknapp, who admitted his players struggled to cope with the artificial pitch at the Neufeldstadion.
"At 3-0 down, we were staring down the barrel. We were in desperate trouble. We were all over the show."
