Many teams think that they will win the World Cup based on their own opinions. When this happens, they are considered to be overrated. Spain and Brazil are probably the most overrated teams in terms of stats for the 2018 FIFA World Cup. Brazil won several games against Russia, Germany, Croatia and Austria, but it lost against Switzerland. Spain won a few games and tied a few games prior to the FIFA World Cup of 2018.
Spain tied friendlies with Germany and Spain. Spain won against Argentina and Tunisia prior to the World Cup. Even though these two teams have many fans and many famous players on them, neither of them won. As a matter of fact, neither of them competed in the finals.
People will always have different speculations on which team they think is the most overrated in the FIFA World Cup. Some say that it is Argentina because in spite of the big stars that they have, the players just cannot work well together.
Some also say that it is Belgium because they are always considered to be one of the top teams but they never get anywhere. There are also some people who say that France is also an overrated team. It has a lot of talent and skills but they still do not know how to use it. They are being hyped and they may not be able to live to that hype.
