After victory over Villarreal, Arsenal wing ace Theo Walcott is convinced Manchester United will be worried ahead of their Champions League semifinal.

He said: "There is a lot of confidence in the dressing room, everyone is buzzing. We feel every team are scared of us as soon as we step on the pitch. It's great to play when things are going like that.

"We are playing brilliant football and scoring goals from all sorts of positions which helps the team.

"We are defending well and even though we have players out injured, others are coming in and doing just as good a job.

"It will be difficult against United but we play them regularly in the Premier League and do very well against them. They are probably the best team in the world but as long as we dig in, I'm sure we'll be fine."
