River Plate vice-president Matias Patanian has denied there has been an offer from West Ham United for defender Eder Alvarez Balanta.
The 21-year-old Colombian defender is currently at the World Cup having helped his nation into the second round with three wins from three group games.
Despite reported interest from the Hammers for the centre back, River Plate vice-president Patanian told Radio La Red: "For the moment we only know, in an official way, that Juventus are making a big effort for Balanta.
Asked about West Ham, he replied: "No, we have heard what an English newspaper is saying about West Ham.
"If the amount of money that the newspaper mentions is true and we receive an offer like that, then River could sit down and start negotiations as it would be close to the amount the club expects for transferring Balanta.
"If the money that is being mentioned in the English media is that, then we will have to listen to them when we receive an official offer.
"Of course we would want to sell our players to the team that gets closest to our value."
