Manchester United's owners the Glazer family have said they are looking for new investment and would also consider selling the club.

Liverpool's owners have said they "would consider new shareholders".

However, no specific clubs are being targeted at this stage by QSI, who also have a minority stake in Portuguese side Braga.

And despite the meeting with Levy, it is being stressed that there was no discussion about QSI taking an equity stake in Tottenham.

A full takeover by the Qataris is unlikely as it would require the sale of PSG. European football's governing body Uefa has rules in place that prevent multi-club ownership.

Under the rules "no individual or legal entity may have control or influence over more than one club" in a Uefa club competition.

They define control or influences as:

• holding a majority of the shareholders' voting rights
• having the right to appoint or remove a majority of the members of the administrative, management or supervisory body of the club
• being a shareholder and alone controlling a majority of the shareholders' voting rights pursuant to an agreement entered into with other shareholders of the club
• being able to exercise by any means a decisive influence in the decision-making of the club

In 2017, RB Leipzig and Red Bull Salzburg - two clubs associated with the energy-drink maker Red Bull - were given permission by Uefa to play in the Champions League together the following season.

American investment group RedBird Capital, which bought Serie A side AC Milan last year, also has a stake in Liverpool's owners Fenway Sports Group.
