If he tries to play a slow passive, possession based style at Goodison then he will fail and eventually be sacked. It will be up to him to show that he has the pragmatism needed to be an Everton manager. He's not who I would pick, but the players are the problem here, not Nuno or whoever else we could appoint.
He absolutely will play slow, plodding, defensive football
It will be as bad as Koeman/allardyce
