LONDON, April 19 (Xinhua) -- Chelsea cut Manchester United's Premiership lead to three points with an easy 4-1 win at lowly West Ham on Thursday.

    Two sublime Shaun-Wright Phillips strikes in the first-half and second half goals from Salomon Kalou and Didier Drogba earned a valuable three points for the Blues.

    The comprehensive victory, coming 24 hours after the Red Devilshad stretched the gap at the top to six points by beating Sheffield United, also spelled doom for the Hammers, who are now second from the bottom and need a miracle to beat the drop.

    Liverpool moved back into third place, two points above Arsenal,after two Steven Gerrard goals settled a 2-0 victory over Middlesbrough. They have 68 points from 34 games, 14 points behind second-placed Chelsea.

    Blackburn have not given up hope of sneaking a UEFA Cup spot after a 3-1 home win over rock bottom Watford.

    The opening 30 minutes at Upton Park were evenly contested, andit took a moment of individual brilliance from Wright-Phillips to break the deadlock for Chelsea.

    He held off Yossi Benayoun and then deceived Jonathan Spector before driving a perfect finish across Robert Green.

    Although a rare Petr Cech slip allowed Carlos Tevez to level for the hosts five minutes later, Phillips volleyed in for the second time to restore Chelsea's lead within seconds.

    Chelsea made it three after 52 minutes, when Frank Lampard's free-kick found Drogba, and even though Green blocked his effort on the line, Kalou was on hand to turn in.

    In the 62nd minute, Drogba wrapped up the impressive display from the champions, shaking off Lucas Neill's attentions to beat Green with ease.
