Aston Villa striker Darren Bent is set to make a loan move to Brighton in the next 48 hours, according to Sky sources.
Juan Cala wants to find 'another club ASAP' and believes Cardiff have acted without respect towards him.
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."
