Inter Milan's sporting director Piero Ausilio has confirmed that talks with Chelsea have taken place over midfielder Fredy Guarin, but no deal has been agreed.
The Colombian international has been a target for the Blues for some time, but they will have to fork out a big transfer fee to secure his signature.
Reports in recent weeks suggested Inter would also be interested in listening to offers which include a swap deal with Juan Mata moving in opposite direction.
Speaking to Sky Sports Italia before Inter's Monday night game against Lazio, Ausilio said:
"Guarin is an Inter player and we are happy to keep him.
"Denying the contacts with Chelsea would be denying the evidence. It is a source of pride to talk with them about one of our players, but everything stopped there," he added.
Last week, Jose Mourinho ruled out signing a top striker during the January transfer window, but telling the Portuguese manager failed to rule out making high profile additions in other areas.
Guarin moved to Inter from Porto, Jose Mourinho's old team, in May 2012 and has contract in Italy until June 2016.
