"I am completely relaxed about it and I think the players are as well."
Wenger also insisted his side are not too heavily reliant on star striker Thierry Henry in European matches.
He said: "The team is of course dependent on Thierry, but overall we are more dependent on big team performances."
Arsenal's reserve goalkeeper Rami Shaaban made his comeback last night after 10 months out following a broken leg.
Shaaban, who made five first-team appearances last season, was beaten twice by Watford's Elliot Godfrey inside the opening 14 minutes in a 2-0 defeat at Barnet.
The return of the Egyptian will be a boost for Wenger who signed the 28-year-old stopper from Swedish side Djurgardens in August last year.
