Scunthorpe manager Mark Robins says his players are buzzing going into their clash with FA Cup opponents Chelsea.
Robins insists they're capable of an upset.
The former Manchester United striker said: "You never know.
"That's why the television cameras are there. But what I would say is that we would have to play beyond our wildest dreams and they would have to have an off day.
"We spoke about calming down in training this week because the players have been going around kicking each other.
"Normally they're more focused than that but, naturally, they're excited at the prospect of playing the current champions."
