Scott Hogan is keen to make a mark at Bramall Lane, having joined on-loan for the rest of the season from Aston Villa.
United made an early start on transfer deadline to secure the services of the 26-year-old and he's excited about the challenge ahead.
He remarked: "I spoke to the Gaffer on Tuesday and I know he's been trying to get me for quite a well now.
"I know he tried hard in the summer and I was very keen coming, unfortunately circumstances stopped the move from happening then, but this month I've done a bit of battling at Villa and I've done all I can to make it happen.
"I'm finally here and I can't wait to get started. There's no hiding from the fact it's been a difficult time at Villa, I've been there two years and had relative success, but personally it didn't really happen for me.
"That's disappointed me, but I knew the manager here wanted me and he wanted me in the summer, when someone wants you as a player it's massive and he's knows about my background and the people around me."
Hogan added: "I've watched United in the last couple of seasons and they are probably the most exciting team to watch in the division, I know a few lads here they enjoy it and there was nowhere else I wanted to go."
