Chelsea had a fierce encounter with Barcelona at the Nou Camp during the Champions League group stage in 2006. After Barcelona went up 1-0 after Deco had given the home side the lead with a well struck long range effort, Chelsea had returned the favor when Frank Lampard chipped a ball right over the goalkeeper from a ridiculous angle. The match ended at a 2-2 draw.
This goal was no fluke. You could tell it was done intentionally by Lampard because he knows there is no one in the box to cross to, so he decided to try to chip it over the goalkeeper, as it was his only chance to beat him. If you happen to have watched the post match interview he said it was intentional and that he had been practicing shooting from these angles.
This goal showed me two things: Lampard has more skills than people would admit and Victor Valdes might be the most overrated goalkeeper in football.
