My personal view is that we did not deserve a win from the match yesterday. Perhaps a draw could be argued for, but you would have to be persuasive.
I think the underlining difference between the sides was how the two reacted to mistakes from one another. United made 3 or maybe 4 mistakes, most of which were VDS fault, but we were never quick enough to react or ruthless enough to punish them. We made one major error, whether it be Rooney not being closed down or Benayoun not pushing up with the rest of the side, and we were punished big style.
It seems we do not, as yet, have this ruthless nature or the ability to make the most of errors made by the opposition, which all top class EPL winning sides have.
Another point I think deserves a mention is the substitutions. I think Benitez got it wrong. Dirk Kuyt was having a bad match, devoid of any confidence, and needed to be taken off around the hour mark or so. You could see that the lad just needed a break from the game. Benitez persisted with him to not only our disadvantage but also a blow for Kuyt.
Overall I do not think we did too much wrong yesterday. There wasn't a massive gulf between the sides. We kept Rooney, Tevez, Giggs and Ronaldo fairly quite for most of the match. I thought we had a tough time in midfield, tougher than expected, but the United CM was on form. The real problem was in the final third, where I think we lacked creativity.
In the 1st half it looked as though Dirk Kuyt did not want the ball. Kewell and Benayoun (who later improved) were off form, in Kewell's case it may have a been a top class game too soon. Torres started brightly but faded in the 2nd half when he was anonymous. I think with a little bit more quality in the final third we may have really tested United.
At the end of the day, you have to give credit to the visitors. They played well in defence and midfield and took their chance, when it came. They were ruthless.
