There's a healthy chance he's been bricked. If so, he needs a reboot. Maybe on the continent to get away from his (and our own) mess.Maybe Kane has personal doubts over things like fitness etc. Perhaps he knew this was his window of opportunity. He probably knew the new generation of strikers were coming through and if he didn't move this season that was it, window shut.
What I don't want is Levy clinging on to him. If he starts playing well again, take the money and reinvest. If he continues to descend, take the money and reinvest. Kane's time with us is done.
