Theo Walcott has backed Arsenal to bounce back from the West Ham disappointment with help from Arsene Wenger’s ability to get belief back into the side.

Accused of turning up for the opening day fixture thinking the points were already in the bag and, perhaps, believing their own hype, the Gunners were some way off the pace and lost the game 2-0.

Frustratingly, the Hammers then did what many teams tend to do after they put in a great performance against Arsenal – play like rubbish in their next game.

Ahead of Sunday’s lunchtime kick-off against Crystal Palace, Theo has added his voice to those of his teammates who believe that they can respond to the small setback experienced on the first Premier League weekend, and has no doubt that Wenger will be able to get them believing again.

“The best thing about the boss is that he always gets the belief back into the squad after a disappointing result,” Walcott told Sky Sports.

“(The West Ham defeat) came as a shock to the system. It’s always difficult to lose matches and, with the first game being at home, people expected massive things from us.

“I felt like a lot of teams didn’t play their best football to be honest and we were one of those teams.

“We’re going to make sure we put it right, and that is the main thing. There’s no point sulking about one game.”
