The Spaniard has been out since he ruptured his ACL against Chelsea in January, less than a month after Rob Holding did the same against Manchester United.

Holding is back in full training and is expected to continue his return with the u23s when they play Blackburn on Monday night.

“One month more,” Emery said about Bellerin when he was discussing how many defenders Arsenal were missing for their 1-0 win at St. James’ Park on Sunday, a result that equalled their cleansheet record away from home in the league last season.

Arsenal are also without Kieran Tierney, who is not expected back for around another six weeks.

Emile Smith Rowe continues his recovery from a groin problem while Konstantinos Mavropanos will be out for at least another 6-8 weeks as his own groin problem continues to cause issues.
