Manchester City midfielder Fernandinho is hoping to enhance his World Cup chances by impressing against Chelsea's fellow Brazilians in the FA Cup fifth round on Saturday.
The 28-year-old earned a recall to the national squad this week for a friendly against South Africa next month after a two-year absence.
It will be a chance to impress coach Luiz Felipe Scolari before he announces the squad that will attempt to win the World Cup on home turf later this year.
Scolari will almost certainly keep a close eye on Sunday's game as the Chelsea squad has a backbone of Brazilian talent in David Luiz, Ramires, Oscar and Willian.
And Fernandinho, who joined City from Ukrainian side Shakhtar Donetsk last June, has made it clear that winning over Scolari, who had a short, unsuccessful spell as Chelsea manager in the 2008-09 season, was high on his list of priorities.
"It is a dream for me to play in the World Cup in my country," said Fernandinho, who has won five caps for Brazil. "It is maybe the most important thing in my career.
"The next one in Brazil might be in a 100 years. It's the only opportunity. I put in my head that if I played well for Manchester City, then I had a chance to get myself back in the national team.
"After a few months with good performances by myself and by my team-mates, it shows they have paid attention in Brazil.
"The Brazilian players at Chelsea sent me messages and congratulated me. They said I deserved this call-up by the national team. And we are friends, so they say I deserved it and I thanked them."
