Chelsea lost top spot in the English Premier League for the first time in more than two months after conceding a late equalizer to Pablo Hernandez in a 1-1 draw with Swansea on Saturday.
Hernandez drilled the ball into the corner of the net in the 88th minute at Liberty Stadium, ending Chelsea's stay on top of the standings since Aug. 22. Manchester United is two points above Chelsea, which could drop to third if Man City wins later at West Ham.
Victor Moses scored his first league goal for Chelsea by heading on Garry Cahill's header from a corner in the 61st minute.
The result caps a bad week in the league for Chelsea after losing its unbeaten status in an acrimonious match at home to United last Sunday.
