Chelsea v Manchester United in numbers
Chelsea host Manchester United on Sunday, when former Blues boss Jose Mourinho returns to Stamford Bridge.
Here, Press Association Sport takes a look at some of the numbers around the Premier League fixture.
2 - Last season's Premier League matches between the sides were both draws, with only two goals scored after Diego Costa netted a stoppage-time equaliser to deny United victory at Stamford Bridge in February.
3 - Mourinho guided Chelsea to the Premier League title three times, in 2004-05, 2005-06 and again after coming back to the west London club in 2014-15.
5 - United and Chelsea played five times during the 2010-11 campaign, which included the FA Community Shield and two Champions League ties as the Red Devils progressed to the semi-finals.
6 - There were six yellow cards, four to United, when the teams played out a goalless draw at Old Trafford in the Premier League last season on December 28, which brought an end to a run of four straight defeats for Louis van Gaal's side
116 - Chelsea forward Didier Drogba was sent off after 116 minutes of the 2008 Champions League final against United in Moscow, which ended 1-1 after extra time. The Red Devils went on to win following a penalty shoot-out but only following a slip by Blues skipper John Terry as he stepped up for what would have been the winning kick.
1907 - Chelsea first played United in 1907, having won promotion to the old First Division two seasons after the club's formation. United went on to lift the title.
