The announcement of the Dutchman as David Moyes' long-term replacement is expected to be made after United host Hull.
Van Gaal will assume the reigns at Old Trafford once his involvement with Holland at the World Cup this summer comes to an end according to the Daily Mail.
The 62-year-old has been continuously linked to the United job and it would now appear that the Glazers have finally got their number one target.
There had been suggestions that the delay for the announcment was due to the former Barcelona boss' demands that he be allowed to bring his entire backroom staff with him.
Gaal's team includes current Holland assistant coach Patrick Kluivert and with their arrivals it is unknown whether the class of '92 will be part of his set-up.
Ryan Giggs is the current interim manager working in tandem with coaches Paul Scholes, Nicky Butt and Phil Neville but Van Gaal may bring in goalkeeping coach Frans Hoek, physio Jos van Dijk and video analyst Max Reckers.
After the Red Devils failed to qualify for the Champions League Van Gaal will be given plenty of funds to ensure that the same does not happen again next season.
And the club believe he will have sufficient time to sign players despite being away with Holland in the early part of summer.
In addition to Barcelona Van Gaal previously managed Bayern Munich so he is unlikely to be daunted by the prospect of not only managing the twenty-time league winners but embarking on a career in England for the first time.
He will be wise to note the influx of players that joined Tottenham last summer as Chairman Daniel Levy splashed £100 million to make up for the loss of Gareth Bale to Real Madrid.
Rumours that Van Gaal may bring in Toni Kroos, Marco Reus and Mats Hummels to name a few are positive but if they all do arrive at United they will need time to adapt and gel with their teammates.
