Spanish daily Marca believes Real Madrid will have to pay more than 19.5million euros to sign the 25-year-old.
The Spaniards are out in the market looking for a new striker after Ruud Van Nistelrooy was ruled out for the rest of the season with a knee ligament injury.
The Spanish side have also been linked with Carlos Tevez, Didier Drogba, Hernan Crespo, Diego Milito and Oliveira in recent days.
