Alex Song maintains Arsenal are ready for what is set to be a highly-charged Champions League encounter against Partizan Belgrade in Serbia on Tuesday night.
The Gunners were shell-shocked by their home Barclays Premier League defeat to West Brom on Saturday, where they had trailed 3-0, and now must look to get their season back on track with a positive result in one of the most intimidating atmospheres in European football.
"Normally we win most games but we have just come here to do our best because we know in the last few days we have not done very well," the Cameroon international said. "We want to show we are ready."
Partizan may have come through three rounds of qualifying to reach the group stages, but the Belgrade side are in good form, with five wins from six to top their domestic table.
Wenger has called on his team, which will be without injured goalkeeper Manuel Almunia, not to let themselves be distracted from the task in hand.
"We realise that we need to be focused in every single game, produce performances in every single game and that is what I believe we have learnt from Saturday," said the Arsenal boss.
The absence of Almunia, who made a number of errors against the Baggies, opens the door for Fabianski - with the Pole looking to take his chance with both hands rather than drop another clanger.
Wenger continued: "For Fabianski, it is another big chance - but you want a goalkeeper or any player to grab the chance when you get it.
"There is only one way to show confidence in a player and that is to put him on the pitch and give him his chance."
