Sheffield United have reportedly joined Celtic in the hunt for Fulham's Lasse Vigen Christensen after their promotion to the Championship.
The 22-year-old has spent half the season on loan at Burton Albion after joining Nigel Clough's side in January along with Cauley Woodrow and only has a year remaining on his contract at Craven Cottage.
The Mail Online are reporting that newly promoted United are keen on signing the Denmark U21 international but face competition from north of the border, as well as Birmingham City.
He has played 13 times for Burton this season, but made seven appearances in all competitions for the Cottagers in the early part of the season.
It remains to be seen whether Slavisa Jokanovic will allow the Dane to leave in the summer, but after falling down the pecking order at Craven Cottage he could be on his way out.
