Proposals for Old Trafford to be expanded to a capacity of 88,000 are likely to be scuppered by Manchester United's desire to back Jose Mourinho in the summer transfer market.
United had plans to increase the stadium from its current 75,000 seats to improve the atmosphere in the stands and the club's corporate hospitality.
While the proposals are under review, a club insider has told Sportsmail that the financial priority is to ensure the manager has the funds he needs to improve his squad.
Mourinho has sought talks with executive vice-chairman Ed Woodward about the subdued atmosphere at the ground, while supporters have criticised Old Trafford's layout, complaining that it does not make for a raucous environment.
