It was confirmed earlier today that the Blackburn Rovers full-back will sign a four-year contract at Carrow Road once the final pieces of paperwork have been concluded.
Speaking about his latest recruit, Hughton believes that the Swedish international has improved his playing squad.
"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," he 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."
