Ozil's brilliant volleyed goal in the 23rd minute of the game played at the Emirates Stadium was enough to see the home side through.
Meanwhile, Gunners stopper Cech thinks that Ozil's current form despite the doubts over his future is a credit to his character. But at the moment, it's very hard.
"So I'm pleased he took the gamble to finish and I'm happy as well that he scored a very important goal".
Next up for Arsenal is a Carabao Cup quarter-final against West Ham before Liverpool visit north London on Friday night. I will not use him on Tuesday but he's available again, Wenger stated as he added on the topic of Theo Walcott, "Theo is 100 per cent, he will play on Tuesday".
So, expect a similar lineup to what we've seen in the Europa League matches this season, meaning the likes of Olivier Giroud, Danny Welbeck, Mohamed Elneny, Francis Coquelin, Mathieu Debuchy, Calum Chambers, and Rob Holding will also get a chance to start. Now we have the opposite problem, with our top class forwards all struggling to put the ball in the net and Wenger has now shifted back to his four defender formation in our last two games. We need to make sure this time we are ready.
"We gave them three points in the first game and we can't give them more points".
