10 times Cristiano Ronaldo stunned everyone with his brilliance while playing for Manchester United

#6 Chelsea: The old-fashioned trick of tricks with Rooney and Giggs

This goal (0:25 in the video) was actually disallowed by the referee. A lot of fans may not remember it. But it deserves a mention for the vintage bag of tricks (and some acting) from Ronaldo, Rooney, and Giggs. It was so ingenious that the referee, Howard Webb, and his linesmen failed to understand what had transpired.

Ferguson's men were playing Chelsea at Old Trafford. The ball went out for a corner, Wayne Rooney took it to the corner flag, put the ball on the quadrant, rolled it outside and walked away. Technically, the corner had been taken and the Chelsea defence was not aware.

Rooney informed the linesman that he had taken the corner. Ryan Giggs seemingly went to re-spot the ball, caught the Chelsea defence napping, ran along the bye-line and put in a sumptuous cross. Ronaldo, like clockwork, steamed in at the right moment and headed the ball into the back of the net.

The goal was a wonderful piece of planning and quick-thinking. It was brilliantly executed by three of the greatest players to have played for Manchester United. It's a pity that the referees could not comprehend what happened and chalked it off.
