Dion Dublin, on BBC’s Match of the Day 2, branded it "the worst performance in the history of the club, ever".
"I’ve been absolutely tonked before, as player and manager," said Lambert. "You just try and win the next game.
"It’s about how they react. That’s the mark of good players and a good team. I don’t think it will affect them long-term. It’s up to myself and my back-room staff to ensure it doesn’t.
"I won’t have a problem doing that, because they’re really hurt. None of them will be feeling great. I know how to handle it."
