Brazil and Argentina are preparing to battle it out in the Copa America final early on Sunday, but instead of focusing and preparing for the match against old rivals, Brazilian forward Neymar Jr. has instead used his time to argue with fellow Brazilians – because some of them will support Argentina when the most successful South American sides meet for the first time in the competition since 2007.Messi catching the last flight to eternal glory, but Neymar stands in his wayA minority of Brazil fans decided to side against their own nation because they would hate to see Lionel Messi miss out on a major international trophy. At 35, the Argentinean free agent may not get many more chances to go all the way in a competition in the colours of Argentina. Neymar went berserk when he heard about this.”I am Brazilian with a lot of pride and love. My dream was always to be in the Brazil national team and hear the fans singing. I never go against, nor will ever go against Brazil if they are competing for something, whether that is in sport, a modelling competition, the Oscars. If it’s Brazil I’m with Brazil. How can a Brazilian do differently? It’s fine, I will respect it, but go f*ck yourselves.”Neymar’s rant on InstagramDespite considering Messi a good friend, Neymar naturally wants to win the precious trophy. That is fine. But using Instagram to insult fans is unacceptable for such a high-profile athlete.Neymar has scored twice in Brazil’s run to the final, while his former Barcelona teammate Messi has three Copa America goals to his name this tournament.Messi is so mighty sportsman that he got Brazilians supporting Argentina 😭😭 pic.twitter.com/d4bSMC1tTw— ʀᴏғʟ📍ᴇᴜʀᴏ🇪🇸🇦🇷ᴄᴏᴘᴀ (@roflmessi_) July 10, 2021 COPA AMERICAThird-place play-offSaturdayColombia – Peru 3-2 (0-1)/Cuadrado 49, Diaz 66, 90+4 – Yotun 45, Lapadula 82/FinalSunday03.00: Argentina – Brazil
