Manchester United star Cristiano Ronaldo has rated his goal to defeat FC Porto in the Champions League quarter-final as his best ever.

The Portuguese winger struck in the sixth minute from 35 yards to put the Red Devils in front and it was the eventual winner and his best goal ever.

"It is the best 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."
