Analysis from Kaveh Solhekol: Why is Man Utd sale taking so long?
Sheikh Jassim Bin Hamad Al Thani is understood to have submitted a fifth improved bid for Manchester United this week.
The club announced in November that the board was exploring strategic alternatives to enhance the club's growth, with a full sale one option being considered.
Sir Jim Ratcliffe and Sheikh Jassim both publicly confirmed initial offers in February and the latter is understood to have this week made a fifth bid to acquire United.
The offer remains for 100 per cent of the club and those involved in Sheikh Jassim's bid have indicated this will be the final bid.
Then in May, a fourth offer - believed to be close to £5bn but shy of the Glazer family's £6bn valuation - was submitted to the Raine Group, the New York-based investment bank overseeing the sale of the club.
The third and final round of bidding concluded on April 28 but, with reports last month claiming a revised offer from Sir Jim Ratcliffe and INEOS had put them in pole position to acquire United, Sheikh Jassim has now moved again.

April 28, 2023: Sheikh Jassim makes world record bid valuing Man Utd. Ratcliffe also makes his offer before the deadline.
May 16, 2023: Sheikh Jassim goes in with fourth bid close to £5bn. INEOS proposal values Man Utd at a higher price but is not for the whole club and would give Glazers chance to keep 20 per cent stake.
June 7, 2023: Sheikh Jassim submits a fifth improved bid and sets Friday deadline.
Sheikh Jassim believes his bid is a very competitive one which brings huge benefits to Manchester United, including clearing nearly £1bn worth of club debt and a separate fund to redevelop Old Trafford, the surrounding area and the club's Carrington training ground.
INEOS values United at a higher price than Sheik Jassim's bid but it is not for the whole club and would give the Glazers the opportunity to keep a 20 per cent stake. United's share price closed down to $18.80 on the NYSE in May, giving the club a market cap of $3.09 billion (£2.47 billion).
"This shows the determination of Sheikh Jassim's Qatari bid and just how serious they are when it comes to buying Manchester United. It's very difficult to say which bid is favourite to succeed because the decision ultimately lies with the Glazers.
"What they have to decide is whether they take all of the money now from Sheikh Jassim or do they want some of the money from Sir Jim Ratcliffe while keeping a stake which would give them more money in the future.
"Are they going to consider what is best for Manchester United or are they just thinking about their own interests? They have to think about what is good for the club because this process has been totally undignified.
"It is unbecoming for a club as big as Manchester United to be treated the way it has. This has been hanging over everyone - the manager, his coaching team, the players - for six months.
"Why has this taken so long when it's been obvious from day one that only two parties were interested in buying the club - Sheikh Jassim and the Qataris, and Sir Jim Ratcliffe?
"The Glazers have to make up their minds very quickly and realise it's not just about what's best for them, it's about what is best for Manchester United. It is now or never."

John Cross from The Mirror and Sam Wallace from the Daily Telegraph joins Teddy Draper on Back Pages Tonight to discuss the latest on the Qataris improved bid in the Manchester United takeover.
The Telegraph's Sam Wallace:
