Brady explained in her diary for The Sun: "Hines, an England Under-21 international, was doing well enough for us here at West Ham - but he wanted too much too soon.
"His agent kept badgering us for more money so we let Hines go to Burnley, who released him in the spring without taking up a year's option on his contract.
"But some players won't learn, or wait.
"Advised by his agent, another player of ours thought he had a future with an Italian club until they saw him play. They said 'arrivederci' and now he's on the market somewhere.
"If you suspect that dud agents are a plague on our game, I'm not going to argue."
