The goal in the video below is  probably Cristiano Ronaldo`s best goal that he scored, of his many, for Manchester United.

Playing in his native Portugal against Porto, and with Manchester United needing to score a goal after a disappointing 2-2 home draw in the first leg, Ronaldo produced this rocket to give Manchester United a 1-0 lead that they never lost, sending them through to the semi finals of the 2009 Champions League.

Ronaldo faces his old club for the first time when Manchester United take on Real Madrid tomorrow night in the Bernabeu in the first leg of their Round of 16 Champions League clash.

Enjoy the goal for yourself in the following video.
