Nigel Clough was happy to see the Blades round off a positive week with a second win in three matches.
Two first-half headers from Harry Maguire and a second-half strike from Ryan Flynn got United's newly appointed manager off to a winning start, much to his obvious delight.
On the 3-1 win over Crewe, which in turn lifted United out of the League One relegation zone, Clough remarked:
"I thought there was a real energy about the performance for the first hour or so, but we just ran out of steam towards the end.
"At 3-0 we knew we had to see the game out though because Crewe will always continue to pass the ball and create chances, which they did for their goal.
"The seven points from the last three matches gives us a solid foundation to build on now, but we will continue to just keep chipping away in the weeks ahead.
"It was vital we beat Crewe to build on the momentum of the Port Vale and Peterborough results, the three goals will give everyone a lift and a clean sheet would have capped it off, but it wasn't to be."
Clough reserved special praise for the Blades two-goal hero on Saturday and the midfielder who chipped with two assists.
The Gaffer added: "It is absolutely vital we score our share of goals from set-plays and with Harry (Maguire)and Neill (Collins) amongst the goals of late takes the pressure of the strikers.
"I have been very impressed with Stephen (McGinn) since we arrived at the club and I know Chris Morgan rates him highly too.
"He actually made the first goal prior to claiming the actually assist. He closed the full-back down, won possession on the flank and then drew a foul on the edge of the area."
