Zanetti, 40, is weighing up whether to play on next season.
"Inter has given me so much and I am very proud," Zanetti said after collecting Fiorentina's Fair Play Cartellino Viola 2013 award.
"Italian football will always be a part of me. In life everyone always does what they feel is right.
"You can make mistakes but then you need to say you're sorry and start again.
"This season I wanted to return from a serious injury, show I can be useful and keep playing.
"The most important thing is the future of this team, qualifying for Europe and finishing the season well.
"Then we will see, I am here and available.
"The bond between me and Inter will last forever.
"At the end of this season, thanks to the great relationship I have with Erick Thohir, we will assess what is best for Inter."
