The 21-year-old, a January deadline day signing from Juventus, contributed his fifth assist for Spurs in Sunday's 5-1 thrashing of Newcastle.
He has also scored two goals in that time and linked up well with the established strike partnership of Harry Kane and Son Heung-min. Conte, who tried to sign the winger when he was in charge of Inter Milan, has long been an admirer of Kulusevski.
"We are talking about a player that I know very well, because he played in Italy," he said.
"He started to play with Atalanta, then Atalanta brought (sent) him on loan to Parma, and he played in Serie A. And he played in a fantastic way."
Kulusevski struggled for game time earlier this season at Juventus, but has already started nine times for Tottenham.
