Friendship will be set aside
Neymar will be putting his friendship with former Barcelona teammate Lionel Messi aside as he chases his first Copa America title with Brazil in Saturday's final.
Messi's Argentina have not won the Copa since 1993, while injury meant Neymar was not part of the Brazil squad which triumphed in 2019.
"Messi is, as I've always said, the best player I've ever seen play and he's a great friend," Neymar said. "But now we're in a final, we're rivals. I want to win and I really want to win this title, which would be my first Copa America.
"Messi has been looking for his first title with the national team for many years, and every time we [Brazil] are not present at the tournament, I cheered for him.
"That's what I've been cheering for in the 2014 World Cup final, when he faced Germany. Now Brazil is in the dispute, so our friendship is on the line [laughs]. The respect between us in still great but only one can win."
He added: "When you're friends with someone, it's hard to forget the friendship you have... but for example when you play video games with a friend, you want to beat him anyway. It'll be the same thing on Saturday."
Neymar also hit out on Instagram at Brazil fans who have turned on the national team. "I'm Brazilian with a lot of pride, with a lot of love. My dream was always to be in the Brazilian national team and hear the fans singing," he wrote. "I've never supported or will support against anything Brazil is competing for, whatever the sport or modelling contest."
