Laurent Koscielny is a doubt for Arsenal as they prepare for Tuesday night's Champions League clash with Bayern Munich.
The Gunners host the German giants in the Round of 16 first leg at the Emirates Stadium but could be without the French centre-back because of a calf problem.
Koscielny has not appeared for Arsenal since February 9 and is touch-and-go for the Bayern test for which winter signing Nacho Monreal is ineligible.
That leaves Arsene Wenger with a gaping hole at left-back as Kieran Gibbs is out with a thigh injury and Andre Santos, thankfully for most Gunners fans, is on loan at Gremio.
