The Greek Football Federation have extended the contract of national team coach Fernando Santos by two years to coincide with the 2014 World Cup.
Santos, 57, was previously contracted until the end of the EURO 2012 campaign and has agreed terms on a deal that will offer security for the next two years.
The Portuguese manager replaced EURO 2004-winning coach Otto Rehhagel after the 2010 World Cup and has reinvigorated an ailing side.
The Greeks are currently unbeaten in 16 international games and qualified for EURO 2012 by finishing at the head of their qualifying group.
Greece were drawn in Group A for this summer's tournament, alongside Poland, Russia and Czech Republic.
