Sign or go.
Put the pressure on the player, not the club, who pay his massive wages.
There's a few players we should have done that to in recent seasons.
He's a good player but probably not as good as he, or his agent, think he is.
I can't think of another top PL club that would want him, unless he is under 30m, so I'm not sure a move away from Everton, who are doing well with Koeman and who are looking to strengthen, would be the right decision for him.
