Barcelona and Real Madrid are two of the biggest football clubs in the world, with both regularly signing some of the best players in the world. New-era stars like Lamine Yamal and Jude Bellingham are following in the footsteps of the likes of Lionel Messi and Cristiano Ronaldo at their respective clubs.

At the opposite end of the spectrum stand Barcelona, who are seen as having spent decades carefully nurturing a footballing philosophy on the pitch. Managers there have a more distinct framework, so it is up to them to tinker it as they see fit, with potentially spectacular results as Pep Guardiola and Luis Enrique have proven.
