ARSENAL midfielder Samir Nasri will be out of action for a month after undergoing minor surgery on a knee injury picked up in Sunday's 1-1 draw with Liverpool.

The 23-year-old suffered a meniscal injury during the match and will now miss games against Blackpool, Blackburn, Bolton and Sunderland.

Nasri missed the first section of last season with a broken leg and will now have to endure a frustrating spell on the sidelines after an impressive display against Liverpool.
