Yeah, this wasn't aimed at you but A LOT of people keep saying that.
Mikel is actually on less than that. He costs 3.9m per year on the FFP budget according to WAGNH. Assuming the amortized fees are now almost zero since he's been here 11 years, that would mean that he's on 75K/wk.
When you factor in the taxes then he'd probably be earning less than Muslera if he is to move to Turkey.
But this argument about his supposed high wages was mentioned even when he was being linked with a move to the Serie A and people even have said in the past that we need to get rid of Mikel because we need to get rid of his wages.
It's prime time that this myth, much like the myth of Jose Mourinho turning Mikel into a defensive midfielder, is put to bed.
