I think the FIFA Club World Cup says a lot about the EPL being the most competitive league there is because of all the top clubs PSG encountered throughout the season only EPL clubs were able to give them much problems. I give Chelsea their flowers for winning the CWC it was worth the journey. Chelsea have done very well by validating that the EPL is a what they say it is.
The Premier League is well-known by football fans as one of the most competitive and difficult leagues. This is due to the abundance of star players in the Premier League, and each club has a substantial budget in each transfer window. It's no surprise, then, that Premier League clubs consistently excel over their competitors. While Premier League clubs don't achieve impressive results in Europe and the world every season, they consistently dominate.
In fact, in the last five Club World Cups, three Premier League champions have come from the Premier League: Chelsea twice and Manchester City once.
