Neill Collins is optimistic that the Blades can go one better than last season in this year's play-off campaign.
Memories of the penalty shootout defeat at Wembley still hurt Collins and the rest of the players, but the Scottish defender insists they are positive of winning promotion to the Championship this term.
United will play at home in the first-leg and Collins doesn't believe that will have a detrimental effect on the final outcome.
Looking ahead, the centre-half said: "With Yeovil losing on Saturday we did have an opportunity to kick on and play away first, if we could have finished fourth, but it wasn't to be.
"I suppose we couldn't be too concerned with who or where we played first in the play-offs because everything was out of our hands.
"Playing at Bramall Lane can be quite intimidating, especially when there is so much on the game, like there will be on Friday.
"Although we can't hide the fact we have struggled to score at home this season, the lads are confident we can head to Huish Park with a lead and then hopefully we can add another clean sheet to the 21 we achieved in the regular season.
"Last season we defended excellently in all three games, kept three clean sheets and still didn't win promotion, I am sure we can go one better with a similar record this time."
Collins has more reason than most to relish another trip to Somerset on Bank Holiday Monday, adding:
"I have fond memories of playing down there from earlier in the season when I captained the side to a win and scored the winning goal too.
"It is always a tough place to play, but at the moment we can't afford to look beyond Friday because Yeovil will come here and give us a really tough first-leg."
