Luton Town boss Rob Edwards is happy with Mads Andersen's arrival.
The Denmark defender has joined from Barnsley.
Edwards said: Mads is someone we've been tracking for a long, long time.
"The recruitment guys have liked Mads for a number of years, he was one of the outstanding talents in League One last year.
"He's at a fantastic age now, he's played a lot of football, he's really experienced, physically fantastic, and an amazing human being as well, which is important to us.
"Everyone knows I talk about that all the time, the human qualities.
"He's a leader, he's someone who's really keen to come and work and continue to improve, but he's going to add a lot of competition in that back-line, which is already a real strength of ours.
"You could see that through last season, we didn't give many chances away, we didn't concede many goals, but with Sonny (Bradley) moving on, Mads comes in and adds real quality in that area of the pitch."
