The Giallorossi are currently sixth in Serie A, six points behind fourth-placed Inter ahead of their meeting at the Stadio Olimpico on Sunday. Speaking ahead of the game, the 65-year-old Zeman questioned the Milan outfit's ability to produce new talent.
"Today, the nation is turning to young people," Zeman told Gazzetta dello Sport. "And it's better that way. Inter have many important players, but I do not think that many young people. In fact they have very few. If they had had more, things would come better for them."
The Aquile come into the fixture after a 1-0 extra-time win over Fiorentina in the Coppa Italia last Wednesday, a victory that earned them a semifinal berth against the Nerazzurri, but Zeman is of no doubt which game against Inter matters the most.
"For me the Italian Cup these days does not count for much, I do not think," Zeman said. "Indeed, the balance of the season will depend on our position in the league more than the conclusion of the Italian Cup.
"We always aim high to reach those ahead of us. Inter are a top team and must be respected. I hope to see the same desire and the same concentration of the first half against Fiorentina."
