The Red Devils have signed Nick Powell, Shinji Kagawa, Robin van Persie and Angelo Henrique this summer so far, but is believed that Sir Alex Ferguson is eager to sign a new left-back as competition for Patrice Evra.
Despite a move for Everton’s Leighton Baines being speculated, it looks like Buttner could well be the required option for the Scottish coach.
“This is really a dream come true,” the defender told regional tv station Omroep Gelderland, translated to English by Sky Sports.
“It was all arranged very quickly and of course I am very delighted. Happily everything is coming to an end.”
The fee is believed to be in the region of €5 million (£3.9 million), with United beating the likes of Southampton, Fulham and QPR to the player’s signature.
