There are more problems to it than this, but we simply aren’t going to be hiring a manager on £200k+ a week* (which he is currently on) as well as buying him out of that £30m contract.
Frankly, with the players we need to sign and financial restrictions, it would be completely negligent unless it was a Pep/Klopp tier manager.
*about 50% of our wage bill if articles are to be believed
