because we wanted someone who would drop on top of their centre-midfield player. He did that well and put in a great shift. He ran his legs off today and deserved the Man of the Match award."
After revealing that Patrice Evra is not happy the second goal is likely to be credited to Nemanja Vidic, Sir Alex admitted he was disappointed to concede so soon afterwards, although he was impressed by the defending that followed.
"I've not seen their goal again," he admitted. "But, to me, it looked a bit soft for us. Once again, the goalie has parried one out and there's nobody following in on the rebound.
"It did lift Liverpool but some of our defending was a bit erratic and desperate at times. But we managed to get through it. There was a period of three or four minutes where they were shoving players into the box and some interchange between players that we had to defend very well.
"We got through that and the name of the game in the big matches are the moments where you have to defend. Today was one of them."
