A power ranking of Europe's top 10 clubs cannot be based on a definitive set of criteria, but instead must be a reflection of a team's success, its history, fan base and spending power.

Not all clubs have wealthy benefactors and instead are based on sound business practice, plus the good will and hard work of dedicated volunteers down the years.
Have the top clubs changed in recent years based purely on the millions of owners? Perhaps, but the game is probably better for it, so no complaints there.
We look at the current top 10 power clubs across Europe, and as it is not a definitive list, please tell us what you think in the comments below—especially as there is a distinct lack of Welsh and Scottish representatives.
