He's been sent on a quest to find Sam the art of attacking football and also the trait of humility. Given that he was advised where to look by Steve Walsh, he could be gone a long time. However, all could be remedied by the appointment of a new manager and DOF, who actually know what they are doing and don't just talk a good game.
In all seriousness, this might shed a bit more light.
Hopefully, he will be playing more next season but under a new Everton manager.
My god, Allardyce waffles almost as much as Martinez
