Brazil striker Fred has admitted he turned down offers from Premier League clubs in the past and has refused to rule out a return to Europe.
The powerful forward, who is set to lead the line for Luiz Felipe Scolari's side when they kick off their World Cup campaign against Croatia next Thursday, returned to his homeland in 2009.
Fred spent four years with Lyon prior to signing for Fluminense and has recently been linked with a possible switch to Barcelona.
"It was a personal choice to come back home," he told the Independent. "I also had offers from Italy and England."
On speculation over a move away from South America after this summer's global showpiece, he added: "Of course, it's a possibility.
"But for the moment I'm totally focused on the World Cup, and giving the Brazilian people their sixth title."
Fred believes playing on home turf will give Brazil a huge advantage this summer, with the support demonstrated by their fans during last year's Confederations Cup success driving them on to success against Italy, Uruguay and Spain.
But the striker understands the weight of expectation which will be on the shoulders of Scolari's squad after the last World Cup they hosted back in 1950 ended with a shock final defeat at the hands of Uruguay.
"We're extremely confident," he added.
"This might be the most important World Cup ever for Brazil. After all, the last time the World Cup was held here we lost. Now we want to exorcise the ghosts of 1950.
"We feel we're one of the favourites for the World Cup, and winning the Confederations Cup has a lot to do with that.
"FIFA say only the first verse of the national anthem should be played before the games. But [last year] the fans continued singing long after the music stopped, and it really inspired the team.
"We started every game at 100mph and steamrollered the opposition. Brazilians live and breathe football, and that will make a huge difference.
"Scolari is like a father to us. He gives us a hard time, but he's got a big heart. The players respect his honesty. He gives us tremendous confidence."
