I am a Manchester United fan and you should take this tip with a pinch of salt because my opinions will be biased.
United will win their 4th consecutive EPL title to ensure a record-breaking season, and will do this in style. While they do have cause for worry at the back with EVDS, Vidic, Rafael, Neville, Evans out, I doubt Birmingham will trouble the defence much because they will hardly get possession anyway. It's just like how Barcelona don't have top quality, world class defenders, but the sheer amount of possession they keep is a part of their defence, and expect to see that from Man Utd today. Alex Ferguson said that 3 months of anger will be unleashed on Birmingham City, and in front of Stretford End, I see lots of goals coming into this match.
Roland's tip: $5 on Man Utd -1.5/2 @ 1.925 = $9.625
