Watch: David Ospina drops ball into own net for awful Arsenal own goal

Watch goalkeeper David Ospina's shocking own goal for Arsenal in the Champions League.

Colombia international David Ospina got his second straight start for Arsenal in the Champions League, but it might be his last for a while if his actions Tuesday play any part in manager Arsene Wenger's future decisions.

Ospina caught a seemingly harmless corner and then dropped it over the line in his own goal to put the Gunners down 2-1 at home to Olympiakos. Theo Walcott had just equalized for Arsenal at the Emirates five minutes earlier before Ospina's mistake. Arsenal went on to lose 3-2 and has no points from its opening pair of Group F games with consecutive games against Bayern Munich up next.

In a pregame interview, Arsene Wenger said Ospina, who started Arsenal's loss to Dinamo Zagreb to open group play, was chosen over Petr Cech because of a minor calf injury that the Czech Republic veteran suffered over the weekend.

Ospina, it seems, wasn't fully right either Tuesday. Watch:
