Chris Wilder was full of praise for his players, following Sunday's victory at Gillingham.
Bradley Dack fired the home side in front in the first-half, but Kieron Freeman levelled matters after the break before skipper Billy Sharp won it in stoppage-time from the penalty spot, much to the delight of the Blades boss.
Wilder remarked: "It's a great feeling and we've won a game away from home, so that's out of the way now.
"We had talked a lot about previous away games and I didn't want any more hard luck stories. I wanted us to play well and win and thankfully we did both.
"We were unfortunate to go behind, it's about small margins and I honestly thought we should have been coming in at half-time in front never mind behind.
"But again the players have shown enormous character and we deservedly won at what is notoriously a difficult place to come."
The Gaffer added: "The squad is healthier now then when we arrived, we have pace, power and aggression, we have competition for places and importantly we have round pegs for round holes.
"We have defenders who can defend and players who can score goals. We need to stop conceding poor goals and be ruthless in both boxes, but we never turn it in and I always thought if we scored the second goal of the game we could go on and win it."
Of his skipper, Wilder finished: "The responsibility of being captain at this club is huge, but Billy handles it very well and second-half he came alive. He showed bottle to step up and win it for us having missed a couple of chances earlier."
