The 40-year-old has made it clear that he aims to stay at the Giuseppe Meazza side after he ends his playing career
The Argentine joined Inter from Banfield in the summer of 1995 and has since developed into a key figure at the Nerazzurri, making over 800 official appearances for the Serie A giants.
"It’s been almost 20 years and it’s been very intense. I’m still proud to belong to this fantastic club and to still be a part of it. Inter have given me everything," Zanetti told the official Fifa website.
"My relationship with Inter one of eternal love, definitely. Those are my honest feelings for this amazing club, for the Moratti family and all the fans.
"It was love at first sight and that feeling has grown stronger with each passing day, week, month and year. The respect shown to me means so much.
"I’d like to stay as part of this wonderful family forever, even after I retire as a player. One thing is certain: I always want to serve and be of use to this club."
Zanetti has made just five Serie A appearances so far this term as he missed a large part of the first half of the season due to injury.
