Newcastle United secured the EFL Championship title when they beat Barnsley 3-0 on the last day of the season, pipping challengers Brighton & Hove Albion to the top spot.
Talksport have reported that the Danish champions have asked for £3.3million for Newcastle to sign the right-back, who joined them permanently last summer following a loan spell from Austrian club Red Bull Salzburg.

The 26-year-old Danish international has been a regular starter for Copenhagen this season as they marched towards the Superligaen title without suffering a single defeat.
He has played 24 of their 26 league games, scoring two goals and assisting eight as they won 19 league games, drawing seven.
Peter Ankersen rose up through the youth ranks at Danish club Esbjerg fB where he struggled to get first team opportunities, eventually leaving to join Vejle Boldklub in the Danish first division.
He was successful with Velje and was eventually sold to Norweigan club Roseborg BK, where he became a regular starter.

In the summer of 2012, Ankersen returned to boyhood club Esbjerg, where he joined up with twin brother Jakob Ankersen, helping the Superligaen club to a fourth-placed finish and Danish Cup triumph.
After two seasons with Esbjerg, he was sold to Red Bull Salzburg, who loaned him to current side FC Copenhagen.
The 26-year-old has been a successful with the Danish champions, working well with left-back Ludwig Augustinsson to provide width and pace to the Copenhagen attack, providing quality crosses for target men Federico Santander and Andreas Cornelius.
Ankersen would add his width and pace to the Newcastle attack, as well as his ability to glide past opposition players and shoot from distance.
If the Danish international is able to bring his impressive form in the Superligaen to the Premier League, then £3.3million will be a small price to pay for such a talented player.
