#3 Gareth Bale - €101 million
The Welshman became the most expensive player in the world when he completed his transfer to Real Madrid in 2013. Success followed soon after as his first season in a foreign country proved to be a highly effective one. Bale scored in the Champions League and the Copa del Rey final to secure Real a double and reaffirm his status as the future of the club.
He then scored in the FIFA Club World Cup final and helped Madrid mount a title challenge. But his fitness and form took a turn for the worse last year. The 16/17 season was a relatively quiet one for the Welshman, with Zinedine Zidane opting for a 4-4-2 formation later in the year, meaning his side no longer needed a winger.
Real Madrid then went on to win back-to-back Champions League titles but Bale did not play a significant role in either of them. Had he continued his rich vein of form, he would have definitely been higher on the list.
Ultimately, Bale's arrival coincided with Madrid’s return to the top of Europe, making him one of the most successful transfers by the Madrid board.
