The veteran defender believes his compatriot would prove a fantastic signing for Inter and admits the forthcoming clashes with Napoli and rivals AC Milan are vital
The Argentina forward has been heavily linked with a move to the Nerazzurri following his inconsistent run of form for Paris Saint-Germain this season after the €64 million [£54m] signing of Edinson Cavani.
Although he is eager to improve his form for the Ligue 1 champions, the 28-year-old has suggested a move back to Serie A could be possible in the January transfer window, and Zanetti says he would be a major boost for Walter Mazzarri's side.
"If we talk about Lavezzi, we're talking about a champion who we would like to have and who a lot of teams could use," said Zanetti.
"The coach will decide and evaluate what is best for the team."
Inter have managed just one win in their last four games in Serie A after a strong start to the campaign and face Napoli and AC Milan in the derby prior to the winter break.
Zanetti feels it is vital his side are able to call upon some of their injured players for the crucial clashes, including Mauro Icardi, who has caught the headlines for off-the-field issues in recent weeks.
"The thing that matters is that Mauro recovers - he is very important for the team," said Zanetti. "[Diego] Milito? I hope that he and [Walter] Samuel can return as soon as possible, hopefully for the derby.
"The games against Napoli and AC Milan could be vital."
