David Ospina forgets rule number one of goalkeeping with absolute clanger

Someone needs to tell David Ospina that if the ball crosses the white line, then it's a goal.

The goalkeeper is in Arsenal's starting 11 after Pter Cech was apparently dropped but the net-minder has done some dropping of his own. The Arsenal goalkeeper made an absolute clanger tonight in the Champion's League as the Gunners hosted Olympiakos in London. The hosts had got back the game thanks to Theo Walcott's equaliser, and were five minutes from heading in at the break level at 1-1, when the Colombian dropped the ball behind his own goal line from a  corner. What a numpty. via GIPHY https://twitter.com/TransferTavern/status/648944839619387392 https://twitter.com/SeanNolan_/status/648942466868117505 https://twitter.com/piersmorgan/status/648942012281040896
