Brazil forward Neymar has hinted the World Cup in Qatar could be the last in his career.
Neymar, 30, featured in the last two World Cups and has yet to win a major title with the national team.
"I'll play like it's the last," Neymar told Globo. "I talk to my father, we always talk, to play each game as if it were the last because you don't know what will happen tomorrow.
"I can't guarantee that I'll play another [World] Cup... I honestly don't know. I'll play like it's the last. Maybe I'll play another one, maybe not. It depends. There's going to be a coaching change and I don't know if that coach will like me."
Brazil coach Tite will step down after the tournament in Qatar and his replacement has yet to be named.
The Canarinha have won a record five World Cups but haven't won the trophy since 2002.
