Ozil was not part of head coach Emery’s squad to face West Ham, with a report emerging during the game that the German had argued with Emery in training.
Emery claimed no argument took place and that Ozil was absent from his squad because of a cold. But sources maintained that the former Real Madrid man had last week been told he must work harder and that his place was in jeopardy.

Ozil was allowed to return home on Friday after informing Emery he did not feel well, although Emery also revealed the 29-year-old was with him and the rest of the Arsenal squad ahead of kick-off on Saturday.
Emery is understood to have been ready to drop Ozil, whether or not he was unwell after substituting him in the defeat to Chelsea, and it remains to be seen whether he can now win his place back.
Arsenal only handed the player a new £350,000-a-week contract, which runs to 2021, in January but Emery does not seem afraid to bench him.
Asked whether Ozil was dropped as a result of a row, Emery replied: “It isn’t true, that information. I don’t know who started it.
“If you ask me, the doctor, or the club. He was sick yesterday. He spoke with me and decided not to play today. He left training because he was going home. He was sick, blocked up with a cold.
“Today he was here. I said come if you feel better and he felt better today. Before the match he was with the team and with me speaking. No problem with the player. Ask the doctor, he can explain better.”
Aaron Ramsey replaced Ozil and Emery made a point of praising the Welshman’s work-rate by saying: “He worked for 90 minutes. He worked each moment the team needed. His spirit and experience is very important. He is a player the other players can give the ball to in difficult positions because he plays with a very, very high personality.”
Goals from Nacho Monreal and substitute Danny Welbeck, as well as an own-goal from West Ham debutant Issa Diop, secured Emery’s first victory since succeeding Arsene Wenger.
“We needed to win and give the supporters three points,” said Emery. “But we need to improve and we must continue to work to improve and find a better balance.”
