Napoli striker Edinson Cavani, a reported summer transfer target for both Chelsea and Manchester City, is worth only half of the release clause written into his contract with the Serie A club, according to former AC Milan star Zvonimir Boban.
The Uruguay international has scored 22 goals in 28 appearances in all competitions for the Naples club and his potent form over the past few years has led to frequent speculation that he join either Chelsea or Manchester City.
Should either Chelsea or Manchester City formalise their apparent interest in Cavani, then they would have to meet his release clause in order to force Napoli into the sale of their most prized asset.
According to Goal.com, an offer of £53 million from Chelsea or Manchester City - or any other team for that matter - would be enough to prise Cavani away from the Stadio San Paolo, although Boban claims such a fee is way beyond the actual value of the player.
"Cavani is a great player," the 44-year-old, who played 251 games for Milan, told Radio Goal.
"However, I do not believe that he is worth £53m on the transfer market. That’s just my opinion, an honest one. Perhaps he’s worth about half of that figure."
Chelsea, meanwhile, are also being linked with a move for Bayer Leverkusen forward Andre Schurrle, with reports last week claiming the Blues had all but agreed a deal that will see the Germany international switch to Stamford Bridge.
Bayer Leverkusen general manager Rudi Voller has since claimed the Bundesliga club would consider selling Schurrle to Chelsea.
