Arsenal have submitted their updated Champions League squad for the knockout stages of the competition, with Danny Welbeck and Per Mertesacker included, while Carl Jenkinson has been left out.

Welbeck and Mertesacker were omitted from Arsenal’s squad for the group stages because of injury but have now been reinstated, replacing Jenkinson and Krystian Bielik, with the latter having joined Birmingham City on loan.

Mathieu Debuchy and Yaya Sanogo are in the squad, as is Santi Cazorla, who is still recovering from injury.

January signing Cohen Bramall isn’t named as he isn’t eligible for the B-List and there isn’t sufficient space on the A-List.

With regards to youngsters, the hugely talented Reiss Nelson is included on the B-List for the first time, as is prolific striker Eddie Nketiah, while goalkeeper Ryan Huddart is also named after returning from his loan spell at Eastleigh. Glen Kamara, who failed to see a loan move to Twente come to fruition, isn’t included.

Vlad Dragomir, Alex Crean, Yassin Fortune, Donyell Malen and Jordi Osei-Tutu aren’t yet eligible for inclusion on the B-List. All players on loan have been left out.
