In last Sunday's Argentina Primera Division match between Gimnasia La Plata and Boca Juniors, something happened that probably hasn't happened before and we probably won't see again. After the ball deflected off a Boca defender, Gimnasia's Sebastian Romero and Marco Perez both executed bicycle kicks at the same time to score a goal. Trying to figure the odds on both players executing overhead kicks in unison to put the ball in the back of the net is enough to make your head hurt, especially considering Perez had to scramble to his feet in order to get there.
