Arsenal boss Arsene Wenger admits they'll need to win all their remaining games to finish in the top four.

Wenger admits the FA Cup semi final win and switching to a back three formation has changed the mood, made them better defensively and given them new belief after their poor recent run.

Wenger said: “What it did was got the focus on the players on something that is concrete to forget anxiety and a little bit of uncertainty.

“Sometimes when a team doesn't do well, just focusing on something different helps to focus on something that might be better. We realised that we have to fight like mad to come back and win our games.

“The top four is open - but what it demands from us is consistency in the results now until the end of the season. It's still possible, but that means we'll maybe have to have a perfect run-in.

“It looks like we will have to win all our games. That has to be the target. To achieve that, we have to win the next one.

“I think the next thing we have to achieve is to transfer the energy level we showed on Sunday to the Premier League. We started well at Middlesbrough, so let's continue that against Leicester.

“The semi-final will give us a bit more confidence. I think it will convince everybody that with the right energy levels and the right fighting spirit, the right togetherness, we can beat everybody.

“Look, it (the semi final) will give us a lift for sure. But then we have to show we can keep that level of energy and that level of desire, of hunger in every single game until the end of the season."
