Chelsea has best record this season vs mid/low ranking premier teams.Wigan has one of the worse records away this season in Premier league.Chealsea got extra day to rest since CL game last Tuesday and by time starting their match know if United won or not today against Arsenal.the bottom line is if United won,they must win to remain close till they host UTD later on in London and if United wouldn't win then by all means they would like to get even closer and at home with 11 wins out of 16 games while Wigan has 12 losses out of 17 away matches and scoring in average once every 2 games away you looking at probbaly 70-75% probabilty for Chelsea to win.According to your line probability by books for chelsea win is even higher and standing at about 85%.imo can't get any other match better than this one this weekend for a parlay,the only disadvantage is the line which is real low,but then again its for a reason.
