Every football fan will tell you their club is the best, but only a select few actually have the proof to back it up.

By proof, talkSPORT means club football's holy grail - silverware. But which sides around the world are the ones that have the busiest trophy cabinets?

There are a handful of clubs that seem to be winning everything in their respective competitions in recent times, with reigning Premier League champions Manchester City and Ligue 1 giants Paris Saint-Germain springing to mind.

But despite their recent dominance, that doesn't guarantee them a spot in the top 20 most successful clubs ever.

talkSPORT.com has taken a deep dive into who those 20 teams are, using the number of trophies and honours clubs have won in their history to decide the ranking below.

The list could change depending on your own definition of a trophy. No league titles below the top-flight are included here, while Super Cup-style competitions are. Without further ado, here is the list of sides that make it into the coveted top 20 most successful clubs from all around the world.
