As the FIFA Club World Cup kicks on we explore some of the lesser known or perhaps unbelievable continental cup stories, including Champions League underdogs, Cup Winners Cup fairytales (don't worry we will explain what that one is for the young folk out there), second division participants and more!

And heck, if you are not familiar with the Champions League structure we will explain that and how it has changed over the years. So kick back, relax, and lets go on a bit of a journey!

Note: this was recorded before some matches in the CWC took place, such as Auckland's tie against Boca or Man City losing to Al-Hilal.
