i would not have imagined that utd would wobble so badly with the title theirs for the taking but their show at stamford bridge was less than impressive and i think chelsea deserved the three points to take them level

Chelsea did play well I agree but United played a significantly weaker team with the second leg of the Barcelona tie in mind. The key moment of the game for me was the unexpected departure of Vidic, because as the game moved on it left Ferguson with less options to change the game now from the bench with the forced substitution. Ronaldo should have had a penalty the moment he arrived on the pitch with Michael Ballack grapling him in the box like a WWE wrestler. I understand why he brought on O' Shea to protect the draw but had Vidic not been subbed, he may have had the opportunity to try to turn the game with the addition of Tevez from the bench.
I am not completly convinced about the penalty award, it seemed as though Carrick did not have his hand raised all that high and I did not feel that there was much intent, Chelsea got a break there big time.
