Chris Morgan felt the Blades fully deserved the 1-0 win over Yeovil Town on Friday night, but was quick to insist the play-off is far from over.
Substitute Callum McFadzean got the crucial goal in the opening minute of the second-half to give the Blades a slender advantage ahead of Monday's return leg at Huish Park and Morgan was keen to praise the performance of his side.
He remarked: "I thought we were excellent throughout, late on Yeovil put us under a lot of pressure as you would expect, but we stuck to our game plan and got the result.
"It was always going to be tight, most first-legs are. We are happy to be one up, but that is only half-time and the players know that.
"The onus is always on the home team to be positive and we did that throughout. We were quickly out of the traps in the second-half and the crowd backed us like they have all season.
"Now it is important that we recover quickly and get ready for Monday."
Speaking in the aftermath of Friday's win, Morgan reserved a special mention for the match-winner and two other youngsters who came off the bench against the Glovers.
He added: "All the first-year professionals that have featured this season have been excellent and they will never let anyone down.
"They have all risen to the challenge and they have had to because the squad has been stretched at times this season.
"It was pleasing to see Callum (McFadzean) take his chance for the goal in front of the Kop, but Joe (Ironside) and Elliott (Whitehouse) have both quickly become men too."
