John O'Shea believes Manchester United could've scored more than the two goals they managed against Roma last night.

"When the back four are playing so well and Edwin [van der Sar] is playing so well, it is easy to slot in because of the experience and the confidence they have," said O'Shea.

"We know that defensively we are very sound and can keep clean sheets, and the pace we have on the counterattack is frightening and that has made the difference. We can feel unfortunate not to have scored a few more goals especially towards the end of the game when they were pushing on to get something back. We can feel very proud of ourselves for our performance because Roma are a good team."
