Zanetti admits he's close to Atletico Madrid coach Diego Simeone.
"Simeone is a friend of mine," the club captain told TV show Undici. "I guess it's possible that he wants to come back to Italy and maybe even coach Inter.
"Rumours about (Walter) Mazzarri? I don't think it's right to place the position of someone like Stramaccioni in doubt.
"He's very young and he's gaining experience with us. It takes time and hopefully at the end of the season we'll be talking about something great that we've achieved."
