Unai Emery announced that Mesut Ozil missed the Arsenal Premier League match with West Ham because "the players here are better for today's game."
It is said that Ozil, who has been in and out of the Gunners' team all season, is missing the game with a knee injury.
But there have also been suggestions that the decision was tactical, and Emery's comment seems to support this.
Ozil is the highest-paid player in Arsenal, but he has not been an outstanding star for Spanish during his time in charge of the North London club.
The winner of the German World Cup was linked to a move away from the Emirates before the January transfer window, with Inter Milan reportedly enthusiastic.
But since then Ozil has said he will not leave Arsenal this month.
It was recently announced that Arsenal has no money to spend in January and, instead, is focusing on loan agreements.
Aaron Ramsey is also scheduled to leave the club at the end of the season in a free transfer, but his departure could release some funds.
A possible departure from Ozil at the end of the campaign, which would again reduce the Arsenal wage bill, would also free up funds.
