Chris Wilder was understandably delighted after seeing Billy Sharp's winning goal at Peterborough send the Blades five points clear at the top of EFL League One.
In an entertaining clash at the ABAX Stadium, United look like having to settle for a share of the spoils despite a dominant second-half showing, until the skipper popped up with his 20th of the campaign with three minutes remaining.
And speaking afterwards, Wilder acknowledged his side had overcome another hurdle in the pursuit of promotion back to the Championship.
He remarked: "It was a good game, involving two teams having a right go at it. It had a bit of feistiness about it, tackles were flying in but both teams played in a good spirit.
"Peterborough started well and they are an expansive team with some excellent offensive players, but we grew into the game and in the second-half we went all out for the victory, leaving ourselves open at times.
"It was end-to-end, we could have got caught, but we wanted the victory and I'm delighted we got it late on.
"It was a big performance and a big result, first and foremost for the supporters who made the trip, but also for everyone connected to the club."
The Blades boss added: "Peterborough had a hell of a lot to play for and we knew we'd have to defend well and we did. Neither goalkeeper was overworked despite our dominance as the game progressed, but what a time to win it.
"It was a good goal, ending with Billy firing home to que mad scenes with the fans, but that's what we're in the game for.
"We were bold and brave in our approach and in the end got our rewards."
