Inter director general Marco Fassone says his club intend to keep a tight grip on Chelsea-target Fredy Guarin.
The London club are ready to offer €15m for the Colombian midfielder, but Fassone insists no deal has been done.
“Guarin has such talent that he would be tempting for so many teams on the transfer market and boss Walter Mazzarri has made him a better player,” the official told Radio RAI.
“Right now, though, we are just talking about rumours. Guarin is a champion who belongs to us and we are keeping a tight grip on him.
“If we make any moves on the market, both in buying or selling, then we will do so with the intention of strengthening the side.”
The Nerazzurri paid €11.5m to Porto for Guarin in 2012.
