Arsenal midfielder Samir Nasri will be out of action for a month after undergoing surgery on his knee, revealed the Premier League club on Wednesday.

Nasri, 23, suffered a meniscal injury during the match against Liverpool last Sunday where Liverpool keeper Pepe Reina's own goal in last minutes rendered Arsenal a 1-1 draw at Anfield in their opening match at Premier League this season.

Nasri failed to grab a place in France's World Cup squad this summer but played in the recent friendly against Norway.
