London:Uruguayan Diego Forlan put Manchester United into the semifinals of the League Cup, notching a second-half goal in the Reds' 1-0 victory over Premier League rival Chelsea. Forlan's seventh goal of the season came off a throughball in the 80th minute from midfielder David Beckham, who started Tuesday night after being out injured for several matches. In two other quarterfinals Tuesday, defending champion Blackburn defeated second-division leader Wigan 2-0, and Sheffield United beat first-division rival Crystal Palace 3-1. Man United won its eighth straight game and Chelsea suffered its first loss after an 11-game unbeaten string stretching back to early October. The near-sellout crowd of 57,983 at Old Trafford saw the Reds reach the semifinals for the first time in since 1994.
