If you were the manager of a top-level football club like Real Madrid or Liverpool and if you were given money by the owners to build a new team, would you spend it on buying 11 Cristiano Ronaldos or Lionel Messis?

Probably not. Even if Ronaldo and Messi are the best players in the world, a successful football team isn't made up of only one type of player. Instead, it's made up of a solid goalkeeper, strong defenders, creative midfielders and sharp strikers. And a good football manager is able to find the right blend of all these qualities and types of players in order to produce a team that consistently delivers the desired results.
