Even though they have the best coach in the world that wi not make them to win the world soon because Brazil had been winning the world cup for long and it is now in the hand of the current team and players to work on there selves to make sure that they bring the cup to Brazil. This is the work of team work so it is not just the work of the coach.
Therefore, a team needs a coach who is competent, intelligent, experienced, and also has high integrity. a coach will form his team to be strong and great, with the system he applies. So, the role of the coach is very vital for a team. of course, even if a team has the best coach, it doesn't mean that a team will achieve success easily. everything requires process, chemistry, teamwork, ethos and systems. the rest, let luck decide.
Speaking of Brazil, this one country has always created very talented generations. Brazil has sufficient resources, either at the 2022 world cup in Qatar or at the 2026 world cup later. Brazil's existence on the world football stage will always be taken into account, and will always be a challenger in every championship. unfortunately, their achievements have declined since the last time they won the world cup in 2002. not because they did not have potential players, but in general, Brazil was handled by an incompetent coach. also, the luck factor is not on their side.
