Sir Jim Ratcliffe is set to watch Manchester United in person for the first time since his proposed 25% purchase of the club was confirmed when they play Tottenham Hotspur on Sunday.
Ineos chief executive Jean Claude Blanc was also at the FA Cup win at Wigan.
Official ratification of the deal is not likely until the end of February.
However, it is part of the deal that Brailsford and Blanc will sit on the football club board and must be told of any significant decisions around key personnel in the interim period.
Ineos representatives spent extended periods at Old Trafford and United’s Carrington training ground last week as they begin to get an understanding of the club.
Ratcliffe addressed staff in a series of meetings as he outlined his determination to restore United to the pinnacle of the English game.
