David Weir has begun to assemble his backroom staff with the capture of Adam Owen from Glasgow Rangers.
New Blades boss Weir was keen to recruit Owen, who takes on the title of 'Assistant Manager - Performance'.
"Adam is one of the most respected men in his specialist field and I'm delighted that he has taken up the offer to join us here at Bramall Lane," said Weir. "With pre-season almost upon us it was imperative to get Adam in as quickly as possible to organise at this vital time."
Owen, 32, specialises in football-specific conditioning and injury prevention techniques. He has attained a degree in Sport and Exercise Science and is recognised as a leading researcher in the area of 'Football Science'. The Welshman, who began his football career as a player with Wrexham, also holds the UEFA Professional Coaching Diploma and, as well as working at Rangers, has held a role with the Football Association of Wales.
Owen also hopes to be one of the first and youngest people in Europe to obtain both the UEFA Pro Licence and PhD in 'Football Science' and is currently working with Lyon University in France.
He commented: "I've had seven fantastic years at Rangers and turned down other opportunities to work elsewhere to join David here at Sheffield United. This is a big progression for me to come into a club the size of this as an Assistant Manager. The aim is, alongside David, is to make sure we develop the club's on and off pitch processes."
