Though I think this is for the common good against covid-19 and a 12.5% salary reduction is low for world-class soccer players, of course Ozil will be a criticism of many people because of the decline in salary because there is no generosity towards humans who are in crisis when this.
I think there are still many players who agree with the salary reduction because they know that difficult situations like this are indeed experienced by everyone so we have to do the best we can.
