Chris Morgan lavished praise on his players after marking his debut as Sheffield United manager with a deserved 2-0 win over Swindon.
Morgan, who made nearly 300 appearances for the Blades as a player before joining Danny Wilson's backroom staff, was handed the reins when the former Northern Ireland international left Bramall Lane in midweek.
Speaking after goals from Chris Porter and Dave Kitson put Swindon to the sword, Morgan said: "If we are going to get promoted then it's going to be through team unity and that's what we had out there.
"Every professional footballer is talented but if you've got that desire and determination to be better than your opponent then that's going to stand you in good stead. That's what we had out there."
Morgan added: "That's an important win for us but I guarantee you there won't be two happier people seeing that result than Danny Wilson and (his assistant) Frank Barlow. It's never nice when people leave because there are people here, myself included, who have a great affinity with Danny and Frank. But the response was excellent."
Swindon manager Kevin MacDonald was left frustrated by his player's performance.
He said: "There were a few choice words in that dressing room because, not for the first time recently, we've produced a performance that wasn't up to scratch.
"We're a good team and we know we can do much better than that. Now it's up to us to go out there and show it in our next match.
"We showed flashes of it against a United team which we always knew was going to be very fired up because of what has gone on in the week.
"But we've got to put that together now over the course of 90 minutes rather than in bits."
