The 27-year-old arrives with a well-travelled career behind him with two Danish league titles and a Danish Cup that came during three and a half years at Copenhagen, where he also made his Champions League debut.
He has spent the past two seasons as Wolfsburg’s first choice, racking up 63 Bundesliga appearances.
