18. Thomas Mueller (Bayern Munich)
A product of Bayern Munich’s youth system, the club have never had to pay a big transfer fee to sign Thomas Mueller, though his rise over the last few years would supposedly see him command offers of around £32.7 to £38.1million. The 23-year-old has many more years at the top and is already one of the best attacking midfield players in the world, proving highly influential as Bayern Munich swept aside all before them this season to win the treble.
