Billy Sharp said that Sheffield United survived a storm at Elland Road to take all three points and climb into the automatic promotion places in the Championship.
Leeds were second and United third going into the crucial Yorkshire derby and it was the home side who dominated the first half, though Dean Henderson in the Blades goal didn't have a great deal to do despite their pressure.
However, they did go close when a neat move found Tyler Roberts in the area and the striker's first-time shot hit the woodwork.
If we can keep performing and grinding out wins we'll have a good chance.Billy Sharp
That was early in the second half but the Blades survived unscathed and were a more resolute outfit as the game went on, having possession of their own.
The decisive moment in the game came in the 71st minute when United took the lead, Sharp was instrumental, getting the ball and finding Chris Basham with the perfect pass, the midfielder letting strike from 20 yards out and finding the back of the net.
The home side went in search of an equaliser to stay second in the table but, in committing men forward they were vulnerable to the counter attack and Sharp was in a good position to take advantage and double the Blades lead only to be fouled outside the area by keeper Kiko Casilla who was sent off by the referee.
That happened as the game entered added time and there was no time for any sustained pressure from Leeds, the visitors holding out for a victory that takes them up to second in the table, a point ahead of Leeds.
Sharp afterwards said the side demonstrated great resilience to survive the Leeds pressure and get a vital result.
He said: "It's a great win at a very good team, they battered us for the first half hour, we thought that might happen - it was a great atmosphere and we stuck at it. We did the job and got three points.
"We've put ourselves in a good position, it's in our hands, if we can keep performing and grinding out wins we'll have a good chance."
The international break means the Blades are back in action in two weeks time when they are back home at Bramall Lane to take on another promotion rival in Bristol City.
United are 4/6 to win with City 5/1 and the draw 14/5. United are 5/1 to win the game 1-0.
