Gareth Bale became the most expensive footballer in history when Real Madrid paid Tottenham £86m for his services last summer - but who will surpass the Welshman as the costliest player of all time?

This takes into consideration their age, potential, current ability and marketability.
Feel free to tell us who else could break the world transfer record in the future.
