8. Andres Iniesta | £45m
Andres Iniesta turns 30 next month, but Barcelona could still fetch a hefty fee for one of their superstar performers.
Despite his advancing years, Iniesta remains one of world football’s elite players, and should stay at that level for at least another two to three years. This is why, if they took the crazy decision to cash in on the Spain international, Barcelona could expect to receive around £45m for the attacking midfielder’s services.
As well as being one of the world’s best footballers, Iniesta is also extremely marketable and one of the most universally-popular figures in the sport.
