Sheffield United manager Nigel Clough is keen to cause another upset and beat Tottenham to the Capital One Cup final.
Nigel Clough: Hopeful of turnaround against Spurs
The League One side welcome Spurs to Bramall Lane for Wednesday's second leg 1-0 down - but after a weekend of FA Cup upsets that included Cambridge forcing a replay against Manchester United, Bradford shocking Chelsea and Middlesbrough sending Manchester City crashing out, Clough retains hope.
He said: "I read some quotes from Bradford players saying the Friday night game, where Cambridge drew 0-0 at home against Manchester United, gave them inspiration and belief, and we are going to try to use the weekend in the same sort of way.
"But the other side of it is that I think it all will have put Spurs on high alert - if the first leg didn't already - that if you are not careful, lower-league teams can cause you a problem.
"Over two legs you get maybe one shot at these teams when they are not quite sure about you, and all the onus, expectation and pressure was on them at White Hart Lane.
"I think they may be a bit more relaxed at Bramall Lane, because they have a one-goal lead and the onus is very much on us now to go and create.
"It will be an unbelievable achievement for the club, as a League One club, to get to the final."
