Chelsea are set to send more players to the World Cup than any other club, with up to 18 stars from Jose Mourinho's side ready to descend on Brazil.
The west London club have had two more players selected for provisional and final 23-man squads than rivals Manchester United, who have 16 stars potentially on their way to South America.
Four of Chelsea's squad have been selected to represent the host nation by manager Luiz Felipe Scolari, with Oscar, Willian, Ramires and David Luiz all in line to play on home soil.
The Blues also have England duo Frank Lampard and Gary Cahill, Spain pair Fernando Torres and Cesar Azpilicueta and Belgian stars Eden Hazard, Romelu Lukaku and Thiabaut Courtois all set for international action next month.
The rest of Chelsea's World Cup contingent is made up of Cameroon's Samuel Eto'o, Germany's Andre Schurrle, Nigeria's John Obi Mikel, Victor Moses and Kenneth Omeuro, Ghana's Christian Atsu and Holland's Patrick van Aanholt.
