Just when Arsenal had a near-clean bill of health, Takehiro Tomiyasu suffered an injury scare which makes him a doubt to face Chelsea.
The Japan international, whose calendar year has pretty much been disrupted by injury and fitness issues, limped off with two minutes remaining on the clock during the 1-0 Europa League win over FC Zurich on Thursday night having only replaced Ben White in the 73rd minute.
Given Tomiyasu's recent history with muscle injuries, it was no surprise that Mikel Arteta swiftly decided to withdraw the Arsenal defender from proceedings in the hope of avoiding any further damage with games against Chelsea, Brighton and Wolves on the horizon before the World Cup break.
