The American goalkeeper failed to clear a ball in his box during the first minutes of Aston Villa's game against Manchester City, sparking all kinds of jokes.

Brad Guzan will surely not like to remember what happened today at Etihad Stadium. The veteran goalkeeper made a huge mistake against Manchester City, which led to Sergio Aguero's 21st goal of the season.

Guzan was given the ball by one of his defenders, and with Agüero getting closer to him, he tried to clear the ball from his box. He failed miserably,kicking the ball with both legs before it ended up going towards his net. Agüero thanked him for the "effort" and scored.

Later in the game, Guzan seemed to be quite nervous, failing to cut some crosses to his box, including a corner kick that he missed completely, which was not transformed into a goal thanks to some sloppy heading skills by Fernando.

Here's how fans and experts will remind Guzan's mistake.
