Jamie Murphy says he felt the time was right to move south of the border to further his career after 11 years with Motherwell.
Hours after concluding the deal which sees the 23-year-old move to South Yorkshire on a three-and-a-half year contract for an undisclosed fee, Murphy completed his first press conference as a Blade.
On the move, he commented: "I have been aware of the interest for quite a while, but after the bid was accepted I came down to Sheffield at the beginning of the week and was really impressed by the training ground and stadium.
"I had the medical and after seeing Bramall Lane my mind was made up that I wanted to become a Sheffield United player.
"I spoke to the Gaffer and (Head of Football Operations) John Stephenson and they both sold the club to me. Having seen everything I spoke to them and I was convinced I had made the right decision.
"The Academy facilities, training ground and stadium are all excellent, even the press room is pretty impressive."
The Glasgow-born forward, equally at home on either flank or playing as a central striker, says he owed it to Motherwell to leave now to ensure they received some reimbursement for his services as he was out of contract in the summer and could have left on a free transfer:
"I really didn't want to leave Motherwell at the end of my contract and them not receive a penny because I have been there so long and the club has done everything to help my progression.
"I have had some fantastic years at Fir Park and the time felt right personally to leave on a high.
"Everyone wants to play at the highest level and I am no different, I see Sheffield United as a Championship club at least and hopefully I can be part of a successful team here."
Murphy, who will wear squad number 23, is available for Saturday's FA Cup third round tie at Oxford United and is determined to hit the ground running, having scored five goals in his last five appearances north of the border.
He added: "First and foremost I need to earn my place in the team and hopefully my versatility can help. I had no qualms about signing a long-term contract because I want to be as successful as the club wants to be, so these are exciting times.
"The FA Cup is a fantastic competition so hopefully I will get the chance to feature at the weekend."
