Ozil was conspicuous in his absence for the 5-1 win.
But Emery explained: "Yesterday he came in with pain and he cannot train yesterday or play today.
"Each training also he can [do it]. For example [we had players playing today who played on Thursday] like Nacho Monreal, Holding, Iwobi and Danny Welbeck. I think with preparation they have the capacity to play a lot of matches.
"They are at a big level in the matches and every player wants to play. They're preparing for that."
Emery hopes to take advantage of the international break.
"Every international break is important also for international team and for the players because they want to stay with their national team and defend the team. For us it's also about continuing our work but with (more calmness) because we have two weeks, but my idea and focus is Leicester.
"Two weeks is more time to prepare for this match and rest some week like this week Saturday and Sunday, but for us it's time for continuing our work everyday with [calmness]."
