Arsenal have been rocked by the news that French midfielder Samir Nasri has suffered a broken leg and will be sidelined for at least two months.
The 22-year-old joined the Gunners from Marseille a year ago and scored seven goals in 44 appearances for the north London club last season.
However, he will now miss the opening weeks of the new Premier League campaign after being injured in training in Austria.
A short statement on the club's official website read: "Samir Nasri has sustained a fractured fibula during this morning's training session at the club's pre-season training camp in Austria.
"The midfielder will be out of action for two to three months."
Nasri's injury comes a couple of days after the Gunners lost striker Emmanuel Adebayor, who completed a big-money move to Manchester City at the weekend.
