Nigel Clough insists everything is to play for in United's Sky Bet League One play-off semi-final tie against Swindon Town, despite admitting the players were hurting following Thursday's controversial first-leg defeat at Bramall Lane.
Nathan Byrne's 94th minute goal gave the Robins the advantage heading back to the Country Ground on Monday, but despite a number of crucial decisions going against his side, the Blades boss remains upbeat about his side's chance in Wiltshire.
He remarked: "We are still very much in the tie, despite conceding the late goal as we did. We are more than capable of going and winning down there.
"We need a goal, but we can't really afford to concede first. We need to be positive but we can't just go there and throw caution to the wind because if we fall further behind the task will become unbelievably difficult.
"It will be interesting seeing how Swindon approach Monday night too, but that's for them to worry about not us."
Concluding his thoughts on the 2-1 loss, Clough added: "We couldn't have put more into the game, everyone put everything into it and we will make sure we are recovered in time to go again on Monday.
"We want to replicate our performance from the first-leg on Monday and hopefully a decision or two goes our way in the process."
