Barnsley have signed Danish centre-back Mads Andersen on a four-year contract. 

The 21-year-old joins from AC Horsens in the Danish top flight for an undisclosed fee. 

Andersen, who is six foot five, is the third new signing of the summer after Luke Thomas and Brad Collins.

With Liam Lindsay set to join Stoke City, Andersen adds reinforcement to the centre-back department.
