Those in the hunt for Manchester United have been told they have 10 days to submit their next bid.
On Thursday, representatives from the Qatari offer, revealed by this newspaper, will head to Old Trafford for presentations while on Friday it will be the turn of rival Sir Jim Ratcliffe.
They will meet members of various departments, including football, financial and commercial, while also taking tours of the club's iconic home and training ground, both of which are in need of significant investment.
Independent assessments of how much would be needed for a makeover - or a makeover or new build in the case of the stadium - will then be made.
