Arsenal fear Bernd Leno won't see action until 2021.

Leno could be out of action for A YEAR with cruciate knee ligament damage.

The German landed awkwardly after an aerial challenge from Neal Maupay during the Gunners' 2-1 loss at Brighton on Saturday.

Leno left the field on a stretcher on 40 minutes and was replaced by Emilano Martinez.

And Goal says there are fears the 28-year-old "has damaged the cruciate ligament in his left knee".

This could mean 12 months on the sidelines with recovery and rehabilitation.
