Independiente have warned West Ham off 17 year-old striker Nicolas Mazzola.

"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," said club chief Leandro Battafarano.

"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."
