He's only on a 2 year deal isn't he? Not insurmountable for these clubs. I wouldn't imagine he's on silly money either.
And I wouldn't say so but if he feels he's been poorly treated he might decide to take one. Imagine Derby have a few quid to spend. And they were just 3 examples, who knows what is around the corner? Even if he doesn't take a job, why treat him like shite? We saw what happened with JDT, he downed tools. I don't see that from Eustace but even marginal drops in passion and enthusiasm can feed down to the players and impact performance.
My point is - we should be backing him and rewarding him for his good work so far. Not dragging our feet, wasting valuable points as the injuries mount and not delivering the players he is mentioning (in less subtle terms) in each passing interview.
