**Mads Roerslev has completed a move from Brentford to Southampton.**
The 26-year-old Denmark international right-back spent six years at Brentford and made 146 appearances for the club.
He featured in their promotion-winning season and went on to make 94 top-flight appearances.
Bees director of football Phil Giles said: “In my opinion, Mads is one of the best signings we have ever made.
“Not only did he agree to come through our B team and demonstrate that pathway, but he represented our first team with distinction and played a huge part in one of our greatest ever days.
“He will always be welcome back and be given a fantastic reception. We wish him well at Southampton and beyond.”
