After victory at Porto, Manchester United's Quintuple bid is back on says matchwinner Cristiano Ronaldo. "We have an opportunity to win everything and we are very confident that we can," said the World Player of the Year.

"We did not play fantastic in the last five or six games but we expect the next ones will be better because of what we did last night."

In beating Porto at the Stadio do Dragao, United became the first English team to beat their opponents on their own ground, with Ronaldo taking centre stage by rifling home from fully 35 yards after just six minutes.

"It is the best goal I have scored," he said.

"It was a fantastic strike and I can't wait to see it again on DVD. I am very happy with it."
