United, Arsenal march to semis

Three English teams have qualified for the semi-finals of the Champions League as Manchester United and Arsenal both won to join Chelsea and Barcelona in the next round.Cristiano Ronaldo scored the crucial goal for United with an unstoppable shot from 40 yards in the sixth minute, giving his team a 1-0 win at FC Porto in the second leg of the quarterfinals, and an overall 3-2 aggregate victory.Arsenal defeated Villarreal 3-0 at the Emirates Stadium to advance 4-1 on aggregate.In the semi-finals, United will play Arsenal at Old Trafford on April 29, and then travel to London for the second leg on May 5.Chelsea and Barcelona both advanced with draws on Tuesday and will play each other in the other semi-final.Chelsea held on to oust Liverpool 7-5 on aggregate after a 4-4 draw at Stamford Bridge, and two-time champions Barcelona advanced past Bayern Munich 5-1 on aggregate after a 1-1 draw in Germany.United coach Alex Ferguson, who was marking his 150th Champions League match in charge of the club, had said earlier this week that he expected more from Ronaldo. The Portugal forward, who was jeered by the local fans with every touch, replied with an impressive individual effort for his second goal of the competition.Ronaldo began his run from just inside the Porto half in the sixth minute and sent a rising shot past goalkeeper Helton and into the top corner."Unbelievable.A magnificent hit. Absolutely unbelievable,'' Ferguson said."The goalkeeper's got no chance.''Defending champions United stretched their unbeaten run in the Champions League to 23 games by becoming the first English team to win at Porto in 12 matches. The English team won a second leg away from home for the first time since 1999, when they went on to win the continent's top club competition.
