1. Bicycle kick for Real Madrid v Juventus: UEFA Champions League Quarter-Finals First Leg

There are goals on this list that are perhaps more important, but this goal personifies the audacity, calibre and sheer will of Cristiano Ronaldo. He's a man of the occasion and his biggest stage is arguably the Champions League where he continues to raise the bar.
On a night when Juventus were expected to at least get something out of Real Madrid at home, they were left stunned by a 33-year-old man twisting in mid-air to make near perfect connection with an overhead kick to arrow the ball into the net. It was by no means an easy feat, but the time and the place made the goal stand out that much more.
It caused the Juventus faithful to rise and give Ronaldo an ovation that could've been a big deciding factor in his decision to move to the Italian giants in the summer.
