Jack Wilshere feels Arsenal have learnt how to grind out wins when they are not playing their best football.

The Gunners came from behind to beat West Ham on Boxing Day before securing narrow wins over Newcastle and Cardiff in their following two Premier League games.

Wilshere believes the team weren't capable of producing these sort of performances in the past and says it will stand them in good stead for the remainder of the campaign.

You're not going to play your best every game, you look at Cardiff in the first half we weren't at our best

"There's been a few games like that this season," Wilshere said. "But it's three points at the end of the day.

"Sometimes you can't always play your best and you have to still win games. You've seen the likes of Man United and Chelsea do that in the past and we're starting to do that now.

"Something clicked towards the end of last season where we knew we had to get fourth, in games we weren't playing well but we were still winning.

"You're not going to play your best every game, you look at Cardiff in the first half we weren't at our best and even in the second half we kept trying and trying and it looked like it wasn't going to come. We tried until the end and we got a massive win. If we keep doing that then we'll be in there."

Wilshere produced a fine display to help Arsenal knock Tottenham out of the FA Cup on Saturday and the 22-year-old was delighted to be on the winning side.

"We know these games are massive for the fans first of all," he said. "We knew it was going to be a tough game and everyone was going to be up for it. I think the main thing is if you win the battle you win the game and we did that today."
