David Weir believes that recruiting Adam Owen last week could be crucial to United's success.
Welshman Owen was Weir's first backroom addition and will take on the title of 'Assistant Manager - Performance'.
Owen is recognised as a leading researcher in the area of 'Football Science', he began his football career as a player with Wrexham, holds the UEFA Professional Coaching Diploma and, as well as working at Rangers for the past seven years, has held a role with the Football Association of Wales.
Weir commented: "Adam will focus on the performance side of things, we want to get all aspects, on and off the field, right at Bramall Lane and Shirecliffe. He is a qualified coach so he can do multiple jobs, which is a major benefit.
"He has great experience working in international football and the Champions League and I believe we're lucky to get him - I was delighted when he accepted my offer to come and work with us.
"Like myself, Adam sees potential in this club and hopefully we turn potential into success."
Weir adds: "Adam will certainly contribute, but I still hope to bring in an another assistant on the football side, it is not a race to get someone else in, it is about getting the right person."
