Tottenham midfielder Lucas Moura hopes to make Brazil's World Cup squad this summer.
Lucas left PSG in January for Spurs.
He told France TV Sport: "Of course, it's a big goal, a big dream. I will always believe in it, fight a lot to achieve this dream.
"It will be difficult because I have not been summoned (since 2016) and in Brazil, there are many options.
"I have to believe it, prepare for it, give it the best, enjoy the opportunities here in Tottenham."
