Chelsea boss Jose Mourinho believes his players' international prospects improve when they pull on a Blues shirt.
Chelsea currently have four Brazil stars among their ranks - David Luiz, Oscar, Ramires and Willian - and the Portuguese manager believes the latter's chances of playing in the World Cup have been increased by joining the west London club.
"When Willian was playing for Shakhtar and Anzhi, he was not going to the national team and certainly when he comes to Chelsea after a couple of months he is selected, so I think for some reason that happens," said Mourinho.
"They have to be at Chelsea to have the honour to be selected."
