"We are bitterly disappointed with the level of performance that we produced today," Hughes said.
"Nottingham Forest fully deserved to win.
"They showed more desire and energy in their play. They forced us into errors and took their chances.
"I didn't expect the other team to show more desire but I am just being honest.
"I am not telling anyone anything they didn't see themselves. I have known the frailties in the team from day one."
