LVG is an idiot. De Gea isn't refusing to play and looks like he'll be ok with staying there for another season. He just won't sign another contract and will leave to Madrid when its over. He hasn't handed in a transfer request which he could have done if he was in a hurry to leave. Instead of using Romero, use up DDG as much as possible and then fling him to Madrid next summer.
More like he doesn't want to forego his loyalty bonus. As for LVG being an idiot, may be, may be not. But he's done the right thing in building his team from the back with a keeper who's there to stay. He's not obligated to try and keep his want away keeper in pristine shape for the sake of his future employers and ambitions.
