Attendees included Manchester United Plc's Executive Vice Chairman Ed Woodward and FC Barcelona's President Josep Bartomeu, a person with knowledge of the matter said.
Europe's top leagues, players and clubs lined up on Wednesday against Federation Internationale de Football Association president Gianni Infantino's plans for two new global competitions saying his approach was rushed and lacking in detail.
Three other European sides are to be picked from a selection including Chelsea, Manchester City, Arsenal, Atletico Madrid, Borussia Dortmund, Paris Saint-Germain, Porto and Benfica. He adds that the Swiss is expected to call an emergency Fifa Council meeting in early June in a bid to get the green light.
Opposition has risen to the proposals, with the PFSC claiming the "hasty timing and lack of concrete information" around the process had concerned them.
"We have spoken to various people about the health and safety aspects of this, the well-being of players and ensuring they are not overworked", Bobby Barnes, the European president of the global players' union Fifpro, told The Times. The main concern was to make sure that there was no extra physical demand on the players involved.
The host nation of FIFA's new tournament would not be the country of the subsequent World Cup, as it has been established until now with the Confederations Cup.
Funding for the new tournament is being put up by a consortium of investors led by Japan's SoftBank and backed by the likes of Saudi Arabia and the United Arab Emirates.
Such a competition could be a game changer for top-level club football in Europe. Would clubs prioritise that over the Champions League?
Personally, I think it's just another money-making scheme from Federation Internationale de Football Association.
Traditionally reserved for young boys who are on the books at professional football clubs, the role will now be carried out by the girls team at Russian Federation versus Saudi Arabia on June 14 in Moscow's Luzhniki Stadium.
It could easily fund a transfer of a decent player in this inflated market.
What are your thoughts on the potential tournament?
