Chris Wilder believes Gary Madine will prove to be a shrewd signing for the Blades during the second-half of the Sky Bet Championship campaign.
The 28-year-old striker has arrived from Cardiff City until the end of the season and Wilder is delighted to have netted his latest recruit.
The manager remarked: "I've heard so much nonsense about what Gary will do to the changing room, but people have got to trust me and I deserve that right.
"We're looking forward to working with Gary, there have been bits and pieces in the past, but I will always look into characters and how they conduct themselves. Gary will add to what we've got off the pitch, but more importantly on it."
Wilder added: "It's a bold decision by the boy too, he could have taken an easy option. There were two or three top end Championship clubs that he could have gone too.
"He's made a brave move that should be respected, he's not took the easy way out and he wanted to make this happen.
"I've spoken to people I trust and respect who have worked with him and every time he's played against us he's been a proper handful."
