Burnley manager Sean Dyche is hopeful that he can further strengthen his squad before the close of the transfer window.
Celtic manager Ronny Deila has confirmed his interest in Sporting Gijon striker Stefan Scepovic.
The Reds have been tracking the 18-year-old for some time, with contact having been made in the past.
Hansen is due to spend a week working with Liverpool's reserve side, as he looks to catch the eye of the Reds' coaching staff.
He is currently back-up to the more experienced Martin Hansen at Viborg, but is considered to be a hot prospect for the future.
"I look forward to trying to impress," Hansen told Viborg's official website.
"It will be a great experience."
