The Swedish left-back has departed Blackburn Rovers to pen a four-year deal with the Canaries and the manager was chuffed that he chose to be a part of the Carrow Road revolution.
"We're delighted with the addition of Martin. He's been playing in England for seven years and is well acclimatised to the Premier League," Hughton told the club's official website.
"He can also play anywhere on the left hand side so he brings us good flexibility in that sense, plus at 25 he's at an age where he has some experience and also some time to improve.
"At this time it's about improving the squad that we have and Martin certainly does that."
