The Giallorossi coach is confident his side will go from strength to strength following its fine victory over the Nerazzurri on Sunday.
Goals from Alessadro Florenzo, Pablo Osvaldo and Marquinho earned his side the spoils and despite securing his first win with the club, the Czech remained modest.
"We played a good match. The team definitely wanted to counter Inter and at times we did that well," Zeman told reporters in the mixed zone after the game. "This result should give us belief, even if we still have room for improvement."
On bitter rivals Lazio's perfect start, he replied "I have to think of Rome. Next we play against Bologna, not Lazio."
