Arsenal boss Arsene Wenger was disappointed to lose Carl Jenkinson to injury during victory at Marseille.

The summer signing from Charlton has been covering at right-back for Bacary Sagna after the latter broke his leg, while Kieran Gibbs is also out with a stomach muscle problem.

Johan Djourou came on out of position at full-back when Jenkinson hobbled off, and Wenger could be short if the news is not good.

"Jenkinson has a knee problem," said Wenger. "He overstretched his knee and we will check that tomorrow."
