All Brazilians have particular reason to keep a close eye on Chelsea, with a quartet of Selecao stars featuring in the first team.
Oscar, Willian, David Luiz and Ramires are all expected to play a part in the World Cup, a tournament won twice by legendary full-back Cafu in 1994 and 2002.
Now an ambassador for the game in Brazil, Cafu can also be found commenting on footballing matters via his Twitter page.
And after Chelsea's game with PSG, during which they dispatched a few Brazilians of their own, Cafu commented that he was excited to see the club in the next round, providing a particular clash is drawn.
Cafu is hoping for a semi-final draw against Real Madrid, which would pit Jose Mourinho against his former club, and sent congratulations to the Chelsea foursome.
Real Madrid vs Chelsea for the semi final matches? That would be a good game to see!— Cafu. (@officialcafu) April 8, 2014
And to be fair, who wouldn't want to see Chelsea versus Madrid, with the possible exception of Mourinho himself?
It would be a tie which has everything, with a personal grudge, Carlo Ancelotti returning to Chelsea - to battle against a boss who he recently had some choice words for. Mourinho could deny Madrid their coveted 10th European Cup, fabled in Spain as 'La Decima.'
