Luton Town have signed Barnsley defender Mads Andersen for an undisclosed fee.
Andersen captained League Tykes last season.
I'm really pleased to get Mads on board. He has been on our recruitment team's list for a long time now," said Luton boss Rob Edwards.
"We watched a lot of him last season and he's performed really well and consistently for a prolonged period in English football.
"He's someone who can play anywhere across that back three for us."
Andersen said: "I'm going to play with my heart. I'm going to try and give everything I can, 100% team player.
"I'll do anything for the team and, hopefully, they can use my qualities and I can help them to show their qualities."
