He wrote on his Facebook page: "Everybody is disappointed because of yesterday's result. However, that's football.
"It's not fair to diss Mesut. Critic is part of sports and this is good -but polemic is not. Picking one player out doesn't help the collective and the whole club neither!
"He's an outstanding player who will make all of us happy in future. A missed penalty won't change that. This happens to me and to every footballer. Friends stand together. So lets go! Poldi."
Ozil himself took to Facebook to apologise for Arsenal's display in the loss to the Bundesliga leaders where goals from Toni Kroos and Thomas Muller have left Arsene Wenger's side with a mountain to climb in the second leg.
