Liverpool have refused to release midfielder Javier Mascherano for Argentina's friendly against Catalunya.
Mascherano, who is captain of Argentina, was named by Diego Maradona in the squad for the showpiece match, which takes place on December 22.
But with Catalunya, who are coached by Johan Cruyff, an autonomous Spanish region and not a country, the fixture is not recognised by FIFA.
And that has prompted Liverpool to withdraw Mascherano, given the fixture comes between the Premier League visit to Portsmouth on December 19 and the visit of Wolverhampton Wanderers on Boxing Day.
