Arsenal fans have been left reeling with the news that key defender Shkodran Mustafi could face "months out" with a thigh problem picked up on international duty.
The Gunners centre-back pulled up just 36 minutes into Germany's 5-1 World Cup qualifying victory over Azerbaijan in Kaiserslautern on Sunday, and the prognosis doesn't look good.
Germany boss Joachim Low said after the match that Mustafi faced "a longer break" on the sidelines following the blow, with Gunners boss Arsene Wenger doubtless left furious.
And he wasn't the only one, with fans left furious as the Gunners face a long spell without one of their key defenders.
Arsenal go to Watford in their first match after the international break on Saturday, and it'll be interesting to see who Wenger turns to at the back.
