Arsenal are confident they can bounce back from a shock home loss to Aston Villa when they visit Fulham in the Premier League on Saturday.
Arsene Wenger's men made a dreadful start to their league campaign, suffering a 3-1 home defeat to a Villa side who only just avoided relegation last term.
But the Emirates Stadium outfit recovered strongly on Wednesday, posting a terrific 3-0 win at Fenerbahce in the first leg of their UEFA Champions League play-off.
Theo Walcott starred for Arsenal, creating two of the goals, and feels his side can beat anyone at their best.
"If everyone works hard for each other we can get the results," Walcott told Arsenal's official website.
"I think at the weekend that probably wasn't the case, and we knew how disappointing it was. You don't want to start a season like that.
"We've forgotten about that and we're concentrating on Fulham. And if we perform like that (Wednesday), with that intensity, we can beat anyone."
Defender Laurent Koscielny suffered a deep cut to the head in the match, but was suspended for the trip to Craven Cottage anyway, while Wenger is also without club captain Thomas Vermaelen as he recovers from a back injury.
Midfielder Alex Oxlade-Chamberlain (knee) is sidelined for up to three months, leaving Wenger short of midfield options with Abou Diaby (knee) and Mikel Arteta (thigh) not expected back any time soon.
Left-back Nacho Monreal has recovered from a back problem though, and featured against Fenerbahce.
Fulham enjoyed a far better opening day to the season as they claimed a 1-0 win at Sunderland thanks to Pajtim Kasami's second-half strike.
New signings Scott Parker and Darren Bent could make their debuts on Saturday. Parker joined from Tottenham for an undisclosed fee in the week, while Bent, on a season’s loan from Aston Villa, did not feature from the bench at Sunderland.
Fulham will be without goalkeeper Maarten Stekelenburg (shoulder) and Kieran Richardson (hamstring), who both limped off at the Stadium of Light, but attacker Alexander Kacaniklic is a chance of returning from a hamstring problem of his own.
David Stockdale is likely to deputise in goal for Martin Jol's side after coming off the bench last week.
Fulham have enjoyed a good record against Arsenal in recent times, losing just one of their last five fixtures.
But Arsenal did win the most recent meeting as Per Mertesacker scored the only goal in a 1-0 win at Fulham in April that saw both sides end the match with 10 men.
