Legally as well, if we have signed and entered into a legal contract we abide by it.
It's no longer a legal contract if neither City or Everton have rights over him.
From a personal point of view, a few years back i left my job to join a competitor. Three months garden leave which was boss, but when i started my new job i was not able to speak to certain customers due to a clause in my old companies contract. I was not employed by them anymore, but legally i was not allowed contact to certain customers for a further six months. It happens, them the rules unfortunately.
You entered that contract. You own your working rights.
Unless Barry entered this contract along with Everton and City (unlikely) then it can't be enforced.
It's not like your old company and your new company had a deal, they couldn't make such a deal. It's not the same thing.
In contract law you can't have a deal if neither of you own the thing.
