Manchester United signed defender Alexander Buttner from Dutch club Vitesse Arnhem, the Premier League team said on its website.
Buttner signed a five-year contract until 2017, United said, without disclosing financial terms. The 23-year-old made 119 appearances for Vitesse over the past four years.
Buttner is the second Dutchman to join United in the past week after striker Robin van Persie signed from Arsenal on Aug. 17.
United opened its season last night with a 1-0 loss at Everton. The Red Devils host Fulham on Aug. 25 at Old Trafford.
