Qatar circling: Will Man United become football's latest state-backed project?

Prospective new owners of Manchester United have until Friday to reveal their interest in buying one of the world's biggest clubs, with a rumoured bid from Qatar sending shockwaves through European football.

United's current American owners, the Glazer family, opened the door to fresh investment in the English giants in November, either in the form of a minority stake or a full takeover.

Deeply unpopular with supporters since they saddled the club with huge debts in a £790 million ($961m) leveraged takeover in 2005, the Glazers are ready to cash out their chips at an enormous profit.

According to reports, they are seeking £6 billion for the three-time European champions, which would smash the record fee for a football club set by Chelsea last year.

A consortium led by LA Dodgers co-owner Todd Boehly and private equity firm Clearlake Capital paid £2.5 billion for the Blues with a further £1.75 billion promised in further investment in infrastructure and players.

To date only British billionaire Jim Ratcliffe, owner of petrochemicals giant Ineos which also controls French club Nice, has come forward publicly as a potential buyer for United.

But reports of a bid backed by Qatar's emir, Sheikh Tamim bin Hamad Al-Thani, refuse to go away.

PSG power and influence

Qatar already wields plenty of influence in European football's corridors of power.

Paris Saint-Germain have dominated French football since a takeover by Qatar Sports Investments - a subsidiary of the state's sovereign wealth fund - in 2011 and lured some of the game's biggest stars such as Lionel Messi, Kylian Mbappe and Neymar to the Parc des Princes.

Nasser al-Khelaifi, president of PSG, is also chairman of the powerful European Club Association.
