The most fascinating, topsy-turvy season in Premier League history comes to a dramatic climax on Sunday when Manchester United meets Chelsea at Old Trafford. It is not quite winner takes all but almost. In a season of unpredictability it is fitting the title race should go to the wire.

When Chelsea trailed United by 15 points on Valentine's Day, even Carlo Ancelotti admitted the Blues were out of the title race. As recently as last week Betfred bookmakers paid out £300,000 to punters who had wagered on United being champions.

Betfred owner Fred Done faces the prospect of a double payout if the Blues repeat last season's success at Old Trafford. A 1-0 victory for Chelsea would put the pair equal on points with Ancelotti's reigning champions having a two-goal advantage.
