Talksport are claiming the exclusive news, saying that the Netherlands boss has agreed to become David Moyes' replacement after the World Cup.
"The fine details have been sorted out for him to take charge at Old Trafford after the tournament in Brazil," the report claims.
However, Manchester United fans might have to wait a little longer before the news is officially confirmed by the club.
According to the BBC, the club will not name their new manager this week.
Van Gaal does however hold a press conference next Tuesday and it is seem highly unlikely that he will face the media at that stage without his future having been clearly mapped out.
TalkSport claim that current caretaker boss Giggs has agreed to stay at the club as part of Van Gaal's coaching staff.
Patrick Kluivert and Danny Blind – who act as assistants to Van Gaal with the national team – are not now expected to join United, which will pave the way for Giggs to take a senior position at the club.
There has been talk of Van Gaal being given a three-year contract at United and part of his remit will likely be mentoring Giggs to become his successor.
Giggs had nothing but warm words for Van Gaal when asked about his potential successor last week.
"He has a brilliant reputation," the United interim boss said.
"He is a successful manager in different countries. Obviously he has taken Holland to the World Cup. He has a fantastic pedigree."
Van Gaal, now 62, will arrive at Old Trafford with one of the most impressive CVs in world football.
He has managed Ajax, Barcelona, Bayern Munich and AZ in the past and has won the league title with every club has managed.
Manchester United would not have to pay any compensation to the Dutch FA as Van Gaal's contract expires after the World Cup.
