I don't see anything about him that would make our better players want to stay. He hasn't won anything and he can't point to elite players who he has successfully improved.
Why would James/Richarlison/DCL stay if they get offers from elsewhere ?
As it happens I think the current squad if held together but with the addition of an basic PL standard midfielder, right back and right winger all with pace would look immeasurably better, especially at Goodison, whoever the manager was.
But holding it together is key.
Unless we are resigned to Richarlison and James leaving and have gone the Orange juice approach of rip it up and start again.
I'm also concerned that he has a played 6 lost 6 record against Liverpool in the premier League. (although to be fair he did knock their kids out of the FA cup, which was beyond Carlo)
