Chris Wilder heaped praise on two-goal hero Clayton Donaldson, following his debut brace at Sunderland on Saturday.
The experienced marksman netted a goal in each half, as the Blades made it three wins on the spin in the Championship.
And Wilder is pleased to have finally landed a striker, he managed in non-league several years ago, whilst also reserved a special mention for the impact of his substitutions at the Stadium of Light.
The manager said: "We're delighted to have got Clayton, he is a good kid and I know plenty about him, I should do, I've tried to sign him enough times.
"Eventually he has said yes to me and the club and as a centre-forward, what better way to make your debut.
"It was two great finishes and we played well, everyone has contributed, from those that started to those that came on.
"Brooksy was superb when he came on and he troubled them. It was a great ball from him to pick out Clayton's excellent run and what a finish.
"John (Lundstram) was positive when he came on and so was Ched towards the end."
The Gaffer added: "The changing room is buzzing and they are together. When you are a team it is priceless, in a world of individual talent and attitudes.
"We've got a team on the pitch that is together, the staff are and most important the supporters are united."
