Maybe
You're wrong, no?
You can't sell someone who doesn't want to be sold. Moving them out of the first team would be a decent start in process of selling them or forcing them out.it's up on Özil and Mkhi futures at club i would gladly sell both and buy Fakir and ESR as backup.
I'm not sure why nobody considered the option of terminating contracts with them, that's more likely than selling them.
