A faltering Manchester United host a resurgent Chelsea in a match likely to decide the outcome of the Premier League title. No pressure.[LNB] To use a sandwich analogy: sweet bread at the top, sour filling and more sweet bread at the bottom Michael Essien on Chelsea's season Victory for United would all but seal a record 19th league title; three points for Chelsea would propel them to the top of the table and put the destiny of the Premier League crown back in the hands of the champions. [LNB]It is a thrilling climax to a remarkable season that has seen Carlo Ancelotti's side claw back a deficit that stood at 15 points less than 10 weeks ago, a revival inspired by a 2-1 victory over United in March's reverse victory. [LNB]United will bank on their extraordinary home record to see off the London club's challenge. Ferguson's men, who beat Chelsea home and away in last month's Champions League quarter-finals, have amassed 49 points out of a possible 51 on home soil this season, and are unbeaten at Old Trafford since April 2010. [LNB]That defeat came at the hands of Chelsea, who leapfrogged their opponents at the top of the table with five games to go and went on to clinch the Double. Squeaky-bum time indeed.
