My assessment ( only looking at players aged over 21 ):
New goalkeeper ( Sanchez will be off ).
Colwill replacement ( if he doesn't sign ).
Mac Allister replacement.
Caicedo stays or new signing.
Lamptey stays or new signing.
van Hecke stays or new signing.
Alzate stays or new signing...
Tony doesn't do release clauses. That's on record. He is a billionaire who believes that release clauses give away control - and he wants to totally have that control.
Yes, someone might make things up about a release clause on twitter.
But it is almost certain that there won't be one.
