The Gunners showed in Italy that manager Arsene Wenger certainly has not lost the dressing room after a dismal few weeks which have included defeats to Ostersunds FK, Manchester City - twice - and Brighton.
Ozil stepped up to that plate in a crunch Europa League last-16 encounter with AC Milan which had been billed as a make-or-break fixture for under-fire boss Wenger . Gennaro Gattuso's seven-time European champions now have it all to do ahead of the second leg at the Emirates in seven days' time.
It was the first goal Milan had conceded in 599 minutes and they should really have been punished further, with Danny Welbeck shooting straight at Donnarumma one-on-one and Mkhitaryan clipping the crossbar with the goal at his mercy. The former Rangers man has this Milan team fighting for each other and Arsenal will have to rediscover their top form if they are to come away with a result.
Arsenal quickly wrestled their way back into the game, their passing and movement causing uncertainty in the Milan defence and their solidity seeing the home attack quickly run out of ideas.

The Armenia global has showed few flashes of brilliance since arriving from Manchester United in January, but showed his quality in a competition where he has thrived since moving to England.
Arsenal without a win in four travel to AC Milan who are unbeaten in 13. He wants his players to be competitive and aggressive: he was like that as a player, so I'm not surprised.
Arsenal fans aren't going into their Europa League clash with AC Milan tonight with any optimism, it seems. The Italians had gone 10 games without losing between these defeats.
That assist saw him reach a notable landmark, with a hand having been played in 100 goals.
