Arsenal continued their impressive run of form with a 3-0 home victory over Villarreal to reach the Champions League semifinals 4-1 on aggregate on Wednesday.

The Gunners, who are unbeaten in the Premier League since last November, will now face rivals Manchester United in the last four after goals from Theo Walcott, Emmanuel Adebayor and Robin van Persie proved enough to see off their Spanish opponents at the Emirates Stadium.

Walcott opened the scoring in the 10th minute when Cesc Fabregas' flick-on deceived the Villarreal defense and the England winger burst through to superb chip the ball over the head of goalkeeper Diego Lopez.

Villarreal went close in first-half stoppage time when Diego Godin headed over the crossbar, but Arsenal made sure of a semifinal place when, on the hour, Van Persie released Adebayor to net his fourth goal in as many games.

Nine minutes later, the Yellow Submarines were finally sunk when Dutchman Van Persie converted a penalty after a foul on Walcott.

The decision enraged Villarreal to such an extent that Sebastian Eguren was sent off after he was shown a second yellow card for dissent.

With Villarreal down to 10 men, Arsenal took their foot off the gas and were able to conserve energy ahead of their FA Cup semifinal against Chelsea at Wembley this Saturday.

"It was really important that we scored early on," captain Fabregas told Sky Sports. "We wanted to keep the pressure on them and scoring early helped us do that.

"At the end, I think 3-0 is quite a fair result, we could have scored a few more but let's not be greedy and we are happy with the win.

"Facing Manchester United is unbelievable for us. To be in the semifinals of the Champions League against maybe the best team in Europe, and the world, we will take it for sure."
