Neymar's international honors include the 2013 Confederations Cup and an Olympic gold medal in Rio in 2016
Brazil star Neymar said Sunday that the 2022 World Cup will be his last as he "doesn't have the strength to put up with more football".
"I think it will be my last World Cup," the 29-year old told DAZN.
"I will play it like it is the last because I don't know if I will still have the mental strength to put up with even more football."
Neymar, who has played in two World Cups and is his country's second top scorer of all time behind Pele, will be 34 when the 2026 tournament rolls around.
"I will do everything to get to the 2022 World Cup in great shape and will do everything to win for my country, to fulfill my biggest dream since I was little," added the Paris Saint-Germain star.
Neymar played in the 2014 World Cup on home soil and scored four goals.
However, he was to suffer a back injury before Brazil were humiliated 7-1 by Germany in the semi-final.
Four years later, in Russia, Brazil were knocked out by Belgium in the quarter-final.
So far, his international honors have been limited to the 2013 Confederations Cup and an Olympic gold medal in Rio in 2016.
Injury ruled him out of the 2019 Copa America which Brazil won. He played in the 2021 Copa America where Argentina triumphed in the final.
Brazil are comfortably placed to reach the 2022 World Cup in Qatar having won all nine of their qualifiers in the South American region so far.
