The talents of Brazilian players have never been lost on the national football scene and in every World Cup appearance there have always been their players who have been able to steal the public's attention. Even though in the next world cup they have to lose Neymar who is no longer in the best condition due to age, Brazil will still be strong and there will be other players who will replace him at the next World Cup. But I'm not sure they can come out as champions and in comparison maybe we can see how they played in the Qatar World Cup.
I would say that Brazil never had any problems with talents and even strong players who belong to the top elite soccer players in the world. In the recent past or during the last few tournaments they had more trouble to build a cohesive team. One that fits together perfectly and that can play as we have been knowing Brazil for a long time. They have a lot of exceptional individual players, but they couldn't build the ties between all these exceptional players and develop a team that feels united and fights as a unit for their success. As soon as they can solve that problem, the times will come back when Brazil is the team that must be beaten in order to win the World Cup.
