United moved to sack manager David Moyes last week after a terrible season at Old Trafford, and it's widely been expected that the former Everton boss would be replaced by van Gaal, formerly of Ajax, Barcelona and Bayern Munich but currently managing the Dutch national team ahead of the World Cup this summer.
In fact, some reports over the weekend suggested that the 62-year-old had already agreed a deal to be the next United boss, only for the Red Devils to come out and deny the story, saying that when they have an announcement to make, they will make it, but at this stage there is nothing to report on the managerial hunt.
And it seems that a stumbling block has arisen in the deal to take van Gaal to the club, as Dutch press speculate that there has been a disagreement between the two parties over the backroom staff available to the manager should he take the job this summer.
De Telegraaf in Holland have tonight reported that van Gaal wants five new members of staff to assist him at Old Trafford - one of which is believed to be former Barcelona striker Patrick Kluivert - but the club are adamant that van Gaal should keep the existing staff.
With former players Nicky Butt, Paul Scholes, Phil Neville and of course Ryan Giggs currently forming the coaching staff at the club, it seems that the board are hoping to groom one of those to become the next manager at the club after van Gaal's reign is over.
The news will also serve as a boost to Giggs' chances of landing the job on a permanent basis, after the Welshman led the team to a 4-0 win over Norwich City at weekend.
