Bale ranked as the worst investment for Real Madrid, according to a study that listed most European players and their calculated market value.

A recently released study by Swiss-based CIES Football Observatory identified the exact market-values of most players in Europe. The Observatory could then determine which investments were financially wise and which were not.

As the worst investment of last Summer ranked Madrid’s purchase of Gareth Bale. Valued at almost £51M, Perez paid about £30M more than the player was worth.

Coming in second place is AS Monaco’s Radamel Falcao. According to the study, the French club paid for the Colombian £25M more than the striker’s real value.Marouane Fellaini comes in 5th, with Manchester United overpaying the midfielder by about £12M. Finally, Soldado closes the list in 10th place, having cost the Spurs just less than £10M over his calculated worth.

CIES Football Observatory also concluded that the absolute best investment of last Summer was Max Kruse, whom Borussia Monchengladbach signed for a bargain from Freiburg due to the existence of a low buy-out clause. According to the study, the striker’s current market value is eight times higher than the €2M paid by the Germans last year.

Rated as worth £10M, the study ranked Manchester United’s Adnan Januzaj, as the highest value player who made a debut in 2013-14, who cost nothing to their club due to the player being a product of the club’s academy.
