Reunited with PSG, Neymar and Lionel Messi will find themselves as opponents on Sunday in Sao Paulo for Brazil-Argentina, as part of the qualifiers for the 2022 World Cup in Qatar.
The meeting marks the first clash between two of the most famous - and highest paid - men on the planet since they became club teammates again.

Parisian leaders will scrutinize the match and the performance of the two stars.
For different reasons: to ensure that "Leo" is recovered from the Martinez attack and that "Ney", who will be 30 in February, very discreet against Chile on Thursday (1-0 victory), finds a acceptable physical condition.
The former Santos star, not spared from injuries in recent seasons, has made a habit of coming back from his summer vacation weighed down by several extra pounds, a conspicuous overweight during the meeting in Santiago de Chile.
Asked about this, the physical trainer of the Brazilian selection Fábio Mahseredjian said that Neymar was "not overweight": "He weighed himself today and respects his weight," he added.
Faced with these criticisms, the PSG striker posted photos on Instagram highlighting his muscles. “The jersey was L. I'm already at my ideal weight. In the next game, I ask for an M jersey, ”he joked.
