Nemanja Vidic admits Manchester United are brimming with confidence after their performance against Portsmouth this week.

"Everyone in the first half was at their best," he told MUTV. "The movement and passing were both unbelievable. We scored two, but we could have scored more. Everyone in the crowd will have enjoyed that game for the football we played, and all the players enjoyed it on the pitch. I just hope we can keep on playing like this."

In the 2-0 win, Vidic's towering performance helped earn United an impressive 19th clean sheet of the season, a source of much pride to the miserly defence.

"We are proud of the way we have defended this season," he said. "We have been strong at the back this season, but we are more compact than last year. We defend as a team, together and for each other. Of course, we are proud. But we have many games still to play, and we have to repeat what we have achieved in the first half of the season."
