Watch: Ronaldo forgets what sport he's playing, attempts to dunk on City

Cristiano Ronaldo just dunked on Manchester City.

The Portuguese icon hit nothing but net during Real Madrid's semi-final second leg at the Santiago Bernabeu, plucking a cross out of the air with his two hands and pushing it downwards into the goalmouth.

Up 1-0, Ronaldo flashed a cheeky smile as his attempted goal was waived off. He avoided the yellow card, since the referee had already blown his whistle for offside.

Still, you have to applaud the effort from the 6-foot-1 point guard forward.
