I like the price Boylesports have on Chelsea 3-1 & United 10/3 to be top of the league after first round of PL fixtures.
3 out of the last 6 seasons either Utd or Chelsea have been top and I think that could go down to 5 seasons if you eliminate the 2004 season when they played each other on opening day. In 2005 both teams also opened up with away fixtures.
This season Chelsea play Hull and Utd play B'ham both at home
2003 - Utd top after opening with 4-0 Bolton at home
Liverpool Chelsea 1 - 2
2004 - Drawn together
Chelsea Manchester Utd 1 - 0
2005 - Everton Manchester Utd 0 - 2
Wigan Athletic Chelsea 0 - 1
2006 - United top after a 5-1 win over Fulham
Chelsea Manchester City 3 - 0
2007 - Manchester Utd Reading 0 - 0
Chelsea Birmingham City 3 - 2
2008 - 2009 Chelsea top with a 4-0 win over Portsmouth at home
Manchester Utd Newcastle Utd 1 - 1
