Arsene Wenger gave David Ospina the start in place of Petr Cech, and that decision could end up costing the Gunners.

With the match tied at one, Ospina made a terrible mistake on a corner kick which put Arsenal behind 2-1 at the break.

The Colombian goalkeeper was out of position on the corner, and couldn’t get back quickly enough to stop the curling cross. Ospina tried to make a catch and push it out, but he wasn’t able to keep the ball from crossing the line as the assistant referee signaled for a goal.

After falling to Dinamo Zagreb in the first match of group play, a second loss would put a huge damper in Arsenal’s chances of advancing, especially with the Gunners still yet to play Bayern Munich.
