The Gunners added several new players to the squad on the final day of the transfer window, while the attacker admits dressing room was "dead" after 8-2 defeat to Manchester UnitedArsenal striker Theo Walcott is confident the club’s deadline day acquisitions will prove the catalyst for a change in fortunes this season.
The north Londoners were busy on the final day of the transfer window, signing Per Mertesacker, Andre Santos, Mikel Arteta, Yossi Benayoun and Park Chu-Young to bolster a squad weakened by the departures of Cesc Fabregas and Samir Nasri.
The loss of the two key midfielders left many fans questioning the direction the club are going in, but Walcott insists he does not share their concerns.
“I'm not worried about the future at Arsenal at all,” he told reporters.
“New faces tend to get everyone bubbling. We all have to lift our spirits and hopefully those new signings will do the job.”
The late flurry of transfer activity at the Emirates was out of character for a club famous for its frugality in the transfer market, and Walcott admits he was taken by surprise.
“I have never seen Arsenal do that in all the years I have been there,” he added. “A lot of teams leave it until lastminute.com so it was interesting to see.
“We got rid of two great players but we've brought a few in and I look forward to seeing them on Wednesday.”
Boss Arsene Wenger may have been spurred into action in the transfer market by the devastating 8-2 annihilation at the hands of Manchester United, one of the heaviest defeats in the club’s long and illustrious history.
Walcott admits the result was difficult to take, but wants his team-mates to show their character with a swift recovery.
“There's no point sitting and sulking about what you could have done better," he said. “The better team won on the day.
“A lot of people dropped their heads as soon as that fifth, sixth, seventh and eighth goals went in. Maybe the organisation wasn't quite there either.
“I wouldn't say we gave up. We tried our best. But Manchester United were very strong and scored some great goals.
“The dressing room was completely dead afterwards. It is hard to recover from that result and it could hurt a lot of players.
“But Arsenal are a big club. You have to be able to react to those sort of moments.”
