The experienced defender remains positive after his side's disappointing performances this season and believes Inter will soon be back among the elite.
The Nerazzurri have been struggling to find their best form this term and sit only ninth in the Serie A table at the moment, prompting club legend Alessandro Altobelli to describe the current crop of players as the worst Inter team he has ever seen.
Zanetti, however, feels they should take the positives from this season and focus on the future.
"President Moratti and the club are working to make sure Inter are soon challenging again," the injured Argentine told reporters.
He added, "Unfortunately it's been a bad season but we have positives to take from it, like [Mateo] Kovacic, for example. He's the present and future of Inter. It's been an unfortunate season but we're thinking about the future. We'll start again with the positives and our young players."
Inter takes on Udinese in its final game of the season this weekend.
