Chelsea forward Eden Hazard would cost more to buy than Ballon d'Or winner Cristiano Ronaldo this summer, according to the latest report by the International Centre for Sports Studies (CIES) Football Observatory.

As part of a comprehensive study of players plying their trade in Europe's top five leagues - the Premier League, La Liga, Bundesliga, Serie A and Ligue 1 - the Belgium international was valued at between £99-110million.

The PFA Player of the Year was second only to Lionel Messi, who is worth up to £207m, while Real Madrid forward Ronaldo completed the top three.

Real Madrid forward Ronaldo's age and the length of his contract means he is valued at less than Hazard

FACTORS CONSIDERED IN STUDY PLAYER Age, position, contract, international status, experience, performance TEAM Competition level, results, achievements Results only include paid transfers, not players out of contract. Players on loan are not included. Data correct up to June 8. Advertisement

The research group applied a number of factors, including a player's age, the length of their contract and the level of their performance as well as taking into account their club's results and achievements, to work out how much the player would be worth in the transfer market.

This would explain why Ronaldo is valued at less than Hazard; the Belgium star is six years Ronaldo's junior and has a contract at Chelsea until 2020 - two years longer than the Portugal international.

Meanwhile, Tottenham sensation Harry Kane, who enjoyed a standout season in which he scored 31 goals for the north London club, is valued higher than his former team-mate Gareth Bale.

Wales international Bale moved to Spanish giants Real Madrid in the summer of 2013 for a world-record £85m fee, but according to the study his value has dropped by half.

Bale has endured a difficult season in La Liga and is now valued at just £42m, while Kane, who has been linked with a £45m-plus switch to Manchester United this summer, is worth up to £44m.

Neymar, who scored 39 goals for Barcelona including one in Saturday's Champions League final, is the fourth-highest valued player in Europe and, according to this report, would set you back up to £73m.

Champions League winner Lionel Messi was unsurprisingly worth more than any other player

Wantaway Liverpool forward Raheem Sterling is the highest-valued England player on the list, coming in at No 6 and despite only having two years left on his contract is worth as much as £60m.

The former QPR youngster, at just 20 years old, is also the youngest in the top 50 and in fact, England boast the four youngest players on the list - Sterling, Kane, Ross Barkley and Alex Oxlade-Chamberlain.

It is generally accepted that the Premier League has fallen behind Europe in terms of quality in recent seasons but the English top flight is actually the best represented league in the top 10.

Juventus midfielder Paul Pogba is being chased by the likes of Manchester United and Barcelona

Hazard and Sterling are joined by Manchester City striker Sergio Aguero, Chelsea's Diego Costa and Arsenal star Alexis Sanchez in the upper echelons of the list.

Highly sought-after Juventus midfielder Paul Pogba, who is being chased by the likes of Manchester United, Manchester City and Barcelona, is seventh on the list.

Another Champions League winner Luis Suarez, who was signed by Barcelona for £75m - the third-highest transfer fee ever - just one year ago is, according to the study, only worth up to £49m.

Meanwhile, as part of the same study, the CIES has also compiled a list of players that are most likely to be sold this summer.

They conclude that QPR striker Charlie Austin is more likely to be sold by his club than any player in Europe.

The 25-year-old former non-League forward excelled during his debut season in the Premier League scoring 18 goals despite playing in a side that was eventually relegated from the top flight.

Lyon striker Alexandre Lacazette also features high on the list of players that will probably be on the move

Liverpool forward Sterling also finds himself high on this list too. The 20-year-old has refused to sign a new contract at the club and informed them last month that he wanted to leave Anfield.

Sterling is fourth on the list of players most likely to be transferred this summer and Manchester City are currently leading the chase for the England international's signature.

Lyon striker Alexandre Lacazette scored 29 goals for the Ligue 1 club this season and has been linked with a host of Premier League clubs including Manchester United and Liverpool and also features in the top 10.
