Manchester United celebrated like champions at Old Trafford after a 36-second opener from Javier Hernandez and a Nemanja Vidic header took them to the brink of a record 19th league title with a 2-1 win over Chelsea.
United flew out of the blocks. Ryan Giggs began the move, stroking a short pass forward for Park Ji-sung, who slipped Hernandez in behind the Chelsea defence to bury his 20th goal of the season into the bottom corner.
was agonisingly close on two occasions, Hernandez should have tucked home Park's far-post cross despite David Luiz's touch. Park himself brought an excellent save from Petr Cech.
Giggs then nipped past Salomon Kalou to the byline before dropping a cross into the heart of Chelsea's box where Vidic strode past fellow Serb Branislav Ivanovic and powered home from close range.
Chelsea got a lifeline when Ivanovic climbed highest to reach a Ramires cross and headed down for Frank Lampard, who prodded home from close range.
United should have snuffed the visitors' lingering hopes out immediately though as Hernandez nicked possession away from Ramires and seemed to have presented Rooney with a tap-in, only for Alex to slide across to make a crucial goal-line clearance.
