Ozil caused a ruckus during the coronavirus pandemic enforced break. He refused to take a wage cut as Arsenal refused to share any information or what will be done with these funds. Toni Kroos echoed his sentiments in Spain.
This standup to the authorities could be the cause of him being sidelined. Josh Kroenke and Co. want to curb their wage budget and getting rid of Ozil will greatly help them.
