A huge positive was Gabriel Martinelli, I liked what I saw today. Probably the worst Bruno Guimarães performance i’ve seen.27232Very poor performance from Brazil.

He has since missed the games against Switzerland and Cameroon.The superstar's absence has opened the door for the likes of Martinelli to flourish. However, the World Cup is not the stage for experimentation. Every coach will want their best players to be present to win the tournament.Neymar is hands down Brazil's best player. While Martinelli flourished on the left against Cameroon, he is no match for Neymar's experience on the world stage. Vinicius Jr. is a key player for any team he plays for. But he is not yet at the level of the Paris Saint-Germain (PSG) superstar.UEFA Champions League@ChampionsLeague Neymar #UCL11126795🇧🇷 Neymar 😀#UCL https://t.co/jJz46n64wwIf the Selecaos are to become six-time world champions, they will need Neymar on the field.After a great start to the tournament, Richarlison's goals have also dried up. Tite's side need attacking prowess. Who better to provide it than Neymar, who has scored 75 goals and provided 55 assists in 122 games for the national team.
