Ozil produced an assist for the friendly victory.
Emery was asked about the midfielder and remarked afterwards: "Our first objective was to prepare for our next match against Newcastle and for the other Premier League and Europa League matches coming.
"They're all very important for us. Every player is an important player. Some players are away with their national teams, others are here, and we have also had two weeks without a match so it's important to keep moving forward in our training and in our matches. Every player is different but they all have lots of responsibility and they all work very well."
