Arsenal welcome back Callum Chambers while Luiz, Tierney, Odegaard and Smith-Rowe are all unavailable against Sheffield United

Arsenal will hope to forget their disappointing outing on Thursday against Slavia Prague in the first leg of the quarter-final in the Europa League when they travel to Bramall Lane on Sunday.

The Gunners will face struggling Sheffield United who are bottom of the Premier League table at the moment.

Ahead of the game, Mikel Arteta will welcome back Calum Chambers. The English international is now back in full training and available for selection, after missing Thursday's match against Slavia Prague due to a slight knock.

ABSENTEES 

Meanwhile, David Luiz is still unavailable 

as he's recovering from a knee operation he underwent last week. 

David is expected to be back to full fitness and available for selection in the upcoming weeks.

Martin Odegaard has been experiencing discomfort to his right ankle since being on international duty. He reportedly missed Thursday's match against Slavia Prague. 

Emile Smith Rowe sustained a sprain to his left ankle during the match against Slavia Prague on Thursday. 

Kieran Tierney sustained ligament damage to his left knee during last weekend's match against Liverpool.

As announced earlier in the week, surgery will not be required and it's hoped that Kieran will be back in full training within four to six weeks.
