TEAM NEWS:
Arsenal:
A win will send the 'Gunners' through to the knockout stages, whilst a draw will also be enough if Vorskla lose against Qarabag. However, Arsenal will be without midfielder Mohamed Elneny (thigh) and defenders Laurent Koscielny (achilles) and Konstantinos Mavropanos (groin), whilst Sokratis Papastathopoulos (ankle) and Nacho Monreal (hamstring) are doubts.
Sporting Lisbon:
Sporting lost out to Arsenal in the reverse fixture, and a win here could send them top of their group. Caretaker manager Tiago Fernandes will be without Rodrigo Battaglia, while Stefan Ristovski and Rafinha are doubts ahead of the game.
WHO IS SAYING WHAT?
Arsenal boss Unai Emery:
"[Sporting] have very good players. They changed the coach but it’s a very big match for them in their thinking about getting the first position. We will go into the game with big respect for them.
"Tomorrow is a very good test for us. We are finding our focus. This competition is very important for us, it is a title and one way into the Champions League next year."
Sporting Lisbon boss Tiago Manuel Matos da Costa Fernandes:
"We know how good a team Arsenal are, especially at home. But we want to bring joy to the supporters that we're bringing to their stadium. The players have been training fantastically, with a lot of professionalism, and that makes me proud to represent the club in this competition.
"If we make any mistakes, Arsenal will try and punish us. We need to be organised and cohesive. The key is to play for ourselves."
