Arsenal’s defensive problems took another turn today with the news that Nacho Monreal has not made the trip to Germany for the Champions League tie with Borussia Dortmund.

At this point it’s not exactly clear what the issue is with the Spaniard, although he missed training today along, it seems, with Calum Chambers.

However, the young Englishman has travelled while Kieran Gibbs will take over from Monreal at left-back.

Short on defenders in the first place, Arsenal look set to be without Mathieu Debuchy for around three months with an ankle injury sustained against Man City on Saturday.

Arsene Wenger has been forced to delve into his youth system to provide cover with Hector Bellerin and Isaac Hayden both involved in this morning’s pre-flight training session.
