My early thoughts:
Over 2.5 Colchester vs Peterboro @ 1.89
There is always goals at Colchester - 43 goals in their 13 home games this season. Peterboro are not goal shy themselves - 10 of their last 13 matches finishing in overs, including 5-0 and 7-0 wins for Peterboro. Aaron Mclean is a goal machine for them, so watch out for him and fellow striker Mackail-Smith has scored 7 goals in the previous two rounds.
Qpr + 2.5 vs Chelsea
Qpr now under billionaire owners. Just bought in a load of players recently and won three of their last four matches, including a 4-2 win away to 2nd place Watford. Since Buzsaky arrived at the club they have slowly climbed up the table. Chelsea still missing a host of players and its a London derby with 6,000 QPR fans present so it won't be a pushover for Chelsea. 2 goal victory at best IMO.
It may be also worth backing against the following:
vs Sheff Utd
Bristol City vs Middlesboro
Huddersfield vs Birmingham
vs Bristol Rovers
vs Crystal Palace
All these teams are odds on but their priorities will be on the league IMO. I guess some of them will rest players and wouldn't mind if they get knocked out.
