The Serb midfielder is being linked with a January move to Como.
Matic and Cesc played together at Chelsea and the latter confirmed contact after Friday night's 1-1 draw with Lazio.
Cesc said, “Yes, I spoke to Nemanja, he is a friend of mine, but so far it is only a chat.
"It is not easy to get these transfers, but we’ll see how the window goes over the next three weeks."
