Arsenal have confirmed that Dinos Mavropanos will be sidelined for four weeks with a groin problem.

The young Greek defender had been expected to feature in the Carabao Cup and Europa League but will now miss at least the next six games. In his absence, Unai Emery will have to rely on Rob Holding, Shkodran Mustafi and Sokratis.

The latter limped off against Everton at the weekend with what looked like a knee injury following a collision with Theo Walcott. Having been assessed by the medical team, it’s thankfully only a dead leg.

We’re assuming the summer signing will miss Brentford’s visit to the Emirates tomorrow but could be in contention for the Watford game on Saturday. Henrikh Mkhitaryan also looks to miss the visit of the Bees, he’s still being assessed after picking up a knock against Vorskla.

Elsewhere, Sead Kolasinac has returned to full training following the knee problem he picked up in pre-season. He’ll provide competition to Nacho Monreal at left-back.

Carl Jenkinson is also back in full training, while Ainsley Maitland-Niles (fractured fibula) and Laurent Koscielny (ruptured Achilles) continue to make progress.
