David Ospina's performance was harshly criticized after the South American goalkeeper scored an own goal to give Olympiakos the lead.

Just when David Ospina needed to prove Arsene Wenger made the right call by starting him against Olympiakos, the Colombian goalkeeper failed miserably during their Group F match against the Greek champions.

Arsenal were not having the best of games after conceding Felipe Pardo's go ahead goal after 33 minutes, even if Theo Walcott equalized just moments later. But Ospina's howler five minutes before the end of the first half handed a serious blow to the team's ego, making them struggle for the remainder of the game.

Alexis Sanchez made it 2-2 with 25 minutes remaining on the clock, but Alfred Finbogasson stepped in and made it 3-2 just a minute later to cancel Arsenal's efforts. Even if the Gunners tried, Olympiakos did not give away to the pressure, securing their first points of the season and leaving Wenger's crew with no points after two games.

Fans had a blast criticizing Wenger and Ospina. Here are some of their best comments.
