Sir Alex Ferguson and Carlo Ancelotti go
head to head at Old Trafford
Man Utd v Chelsea"United will lose pole position on goal difference if Chelsea win at Old Traffford "
This has suddenly become a key fixture in the battle for the Barclays Premier League crown. United's defeat at Arsenal means they will lose pole position on goal difference if Chelsea win at Old Traffford .
United though have dropped only two points at home all season and have the cushion of knowing a draw would surely be enough to see them go on and win their 19th title.
The Blues enjoyed a 2-1 victory in the Barclays Premier League meeting at Stamford Bridge in March but United won both legs of the Champions League quarter-final.[BPL]
