• Drogba scores first league goal since March 2012
  • It was his first league start in two-and-a-half years
  • Chelsea have won seven of nine league games
  • Man Utd four unbeaten at Old Trafford

Robin van Persie's stoppage-time strike earned Manchester United a point in a pulsating encounter with Chelsea.

The league leaders dropped points for just the second time this term when the Dutchman rammed in after Marouane Fellaini's header was saved by Chelsea goalkeeper Thibaut Courtois.

Didier Drogba's header had given Jose Mourinho's men the lead but Branislav Ivanovic was sent off late on.

Chelsea are now four points clear of second-placed Southampton.
