United have long been linked with the two players and are reportedly keen on signing them ahead of the new season.
United know that they may have to smash their transfer record of £30.75million twice in the coming weeks if they are to sign Fabregas and Bale, according to the Times.
United boss David Moyes has recently confirmed his interest in signing Fabregas, while Bale has been a long-term target.
Reports on Friday suggested that Bale would be interested in a move from Spurs to Manchester United.
