With just one round of fixtures remaining in Serie A, Inter are assured of second place ahead of Napoli, although they will be sorely disappointed at losing their crown to city rivals AC Milan.
While the club has not had problems scoring goals this season, leading the Serie A with 66 goals, it is at the back where they have had problems, conceding 41 goals, which is the worst record of the top three sides.
Suprisingly, Inter have been linked with a move for any defenders so far, and instead, all the transfer talk that has been circulating involving attack-minded players.
Manchester City's Carlos Tevez, Lille's Eden Hazard and Udinese's Alexis Sanchez are three of the names that have been regularly suggested as likely transfer targets for Inter, and Zanetti believes all will be good additions at the club.
"Tevez, Hazard and Sanchez are all three excellent players," the Argentinean international revealed to La Gazzetta dello Sport.
Zanetti believes Tevez has an outstanding goalscoring record wherever he plays, while Hazard is showing plenty of promise.
"Carlito [Tevez] has always done very well. He has scored lots of goals at every club where he has played.
"The Belgian attacker [Hazard] is not as well known as the other two, but he has great statistics."
However, Zanetti made no secret of his admiration for Uruguayan forward Sanchez, whom he believes has already shown his capability to succeed in Italian football.
"Sanchez, however, has already shown that he has what it takes to be successful in Serie A.
"I know him very well as I have played against him several times.
"I am confident that he is ready to make the next step and can make the difference at a bigger club."
While Udinese finished 15th in Serie A last season, they have shocked all with their revival this campaign and currently sit in fourth spot, two points ahead of Lazio and on track for UEFA Champions League football next season.
A key factor behind their stunning performances this season has been the form of Sanchez, who has formed a lethal partnership with Antonio Di Natale up front, notching up 12 goals and 12 assists in 27 appearances despite not being an out-an-out striker.
