Arsenal manager Arsene Wenger has urged his players to forget Saturday's impressive win away at Watford and to focus on Tuesday's Champions League game.
The Gunners host Bayern Munich having lost both their opening two games.
They desperately need a win to keep their qualification hopes alive as they currently stand last in Group F of the competition.
"[There was] the one that won the treble with Ribery at full power, Robben at full power and Kroos, Schweinsteiger and Muller in midfield so I believe we have played good Bayern sides and got good results against them," Wenger told reporters on Monday.
"We have the needed belief and confidence that we are doing something right so that helps.
"We maybe could be a little suspected of not taking the first two games seriously enough but this time that is not the threat.
"Let's take the positives of our Premier League [form] and as well get the right focus that you get when you play a big opponent.
"We have some ground to make up in Europe as we have not been at our requested level in our first two games.
"Our focus has been much stronger in the Premier League than it has been in Europe and we know in this game the focus needs to be exactly the same than in the in Premier League."
