Sheffield United boss Nigel Clough was left disappointed by their FA Cup replay defeat to Preston.

The result sets up a fifth round tie for Preston against Manchester United.

"I'm bitterly disappointed," Clough said. "For Manchester United, the biggest club in the country, to come to town as a League 1 club was a massive incentive.

"But we didn't play like that was the carrot at the end of the tie.

"Maybe we thought the tie was over when we brought them back here but that is never the case against a team like Preston."
