Independiente secretary of sport Leandro Battafarano claims there is no truth that teenage forward Nicolas Mazzola has travelled to England to train with West Ham.
Hammers coach Alan Curbishley recently admitted that the 17-year-old has been training at Chadwell Heath but that any interest in the player would be for in the long term.
'He is a young boy we have had training with us,' said Curbishley. 'He is only a 17-year-old. He is nothing for the first team at the moment.'
However, Battafarano insists it is the first time he has heard the Argentina under-17 international is with the English Premier League side, instead insisting he is currently taking part in pre-season training with Independiente.
'As far as we are concerned, we have not been told about Mazzola going to England,' he told PA Sport. 'He is having pre-season training with the first team in Mar del Plata now.
'We haven't set a transfer fee because we are not planning to sell him anywhere. We want to enjoy his skills in the first team here.'
Mazzola, who played at the under-17 World Cup in South Korea last year, has been attracting interest from a number of clubs abroad, particularly from England, but Battafarano refused to disclose whether any offers have been made.
He added: 'I cannot say now whether there was an official West Ham offer, but he is a very good player and a lot of teams have made different offers.
'Several of them were English clubs, and there was not just one.'
