For the festive period, Arsene Wenger will have a fairly large squad given the return of some of his injured players.
According to report.
Arsenal captain Per Mertesacker is back training with the first team after recovering from serious knee injury.
The defender has been out of action since pre-season and underwent surgery on his knee in August.
The German is not expected to return until the new year as he attempts to reach full fitness.
The former Germany international arrived at The Emirates in 2011. He has gone on to register 145 league appearances for The Gunners scoring five times.
His return to full fitness is a timely boost for manager Arsene Wenger. Arsenal suffered a defensive blow last week when summer signing Shkodran Mustafi limped off with a hamstring injury. The German is likely to be out for three weeks.
Gabriel who had been filling in at right-back registered a shaky display as his side lost 2-1 away to Everton.
