Arsenal boss Arsene Wenger says he is not interested in Sunday's big game against Manchester United ahead of today's Champions League clash against Olympiakos.
The Gunners desperately need to take all three points from the Emirates after suffering a shock first-day defeat against Dinamo Zagreb.
"Yes, you sum it up well [this is a must-win game]," Wenger told reporters on Monday afternoon.
"You have to win your home games if you want to qualify from the group stage, it is simple as that. We cannot afford to drop points now against anyone at home.
"[Playing at home] is not much different. What changes more is the attitude of our opponent. We always try to play and go forward.
"At home we face maybe a different kind of problem, teams regroup in front of their box and you need to be penetrative with your passing, with your movement, and clinical with your finishing.
"The [upcoming Manchester United] game will not interfere with that at all. It is more the games we played before that could have an influence.
"Some players had two tough games at Tottenham and at Leicester, where they were a high level physically. I will have to analyse that today and make my decisions."
