Barcelona's Lionel Messi is the most valuable player in the world,
well ahead of Real Madrid's Cristiano Ronaldo, according to a study by
the International Centre for Sports Studies (CIES) Football Observatory.
The study used an algorithm based on 1,500 fee-paying club transfers
since 2009 to determine that Messi's current transfer value is 220
million euros, while Ronaldo trails far behind at an estimated 133
million euros.
Messi, 27, has been increasingly linked with an exit from Barcelona, with both Manchester City and Chelsea reportedly interested in signing the four-time Ballon d'Or winner.
The Argentina captain endured a frustrating 2014 as Barcelona lost
the Copa del Rey final and were beaten to the Liga title by Atletico
Madrid, before Messi finished the World Cup with a runners-up medal
after losing the final to Germany.
By contrast, Ronaldo, 29, lifted the Champions League trophy with
Real Madrid and ended the year with over 60 goals in La Liga, with many
observers backing him as the heavy favourite to lift the 2014 Ballon
d'Or -- FIFA's top individual award which the Real Madrid forward will
contest with Messi and Bayern Munich goalkeeper Manuel Neuer.
Chelsea have three representatives in the study's top 10, with Eden
Hazard (99 million euros) third in the list, Diego Costa (84 million
euros) fourth, and Francesc Fabregas (62 million) eighth.
Juventus midfielder Paul Pogba is reportedly worth 72 million euros
after leaving Manchester United for nothing in 2012, while CIES believes
Raheem Sterling would set Real Madrid back some 63 million euros should
they decide to target the Liverpool forward.
There are six Premier League players in the top 10 overall, with
Manchester City talisman Sergio Aguero (65 million euros) sixth and
Arsenal star Alexis Sanchez (61 million euros) ninth.
Gareth Bale is valued at just 60 million euros by CIES after signing
for Real Madrid for around 100 million euros in the summer of 2013,
although Los Blancos have the most representatives in the top 100, with 11 players.
The variables included in CIES' econometric model refer to player
performances (matches, goals, dribbles, etc.), their characteristics
(age, position, contract duration, etc.), as well as competition level
and results achieved by both their clubs and national teams.
