Manchester held by Swansea as Chelsea routs Villa 8-0
United’s run of five consecutive league wins was brought to a halt in south Wales when Michu canceled out Patrice Evra’s opener for the visitors.
The game ended in acrimony, with United manager Alex Ferguson saying Swansea captain Ashley Williams “could have killed” striker Robin van Persie with a clearance.
United is four points ahead of Manchester City.
The match at Stamford Bridge saw seven different Chelsea scorers in a victory started by Fernando Torres after three minutes.
David Luiz, Branislav Ivanovic, Frank Lampard, Ramires (twice), Oscar and Eden Hazard also scored as Chelsea went third.
