The Inter boss says there are similarities between himself and the Portuguese, while comparing new signing Hernanes to Napoli star Marek Hamsik.
The Italian came up against the Portuguese when Inter faced the Blues in a preseason friendly in America, and it was there that he was struck by similarities between himself and the former Nerazzurri boss.
"I was glad to be able to introduce myself to Mourinho after the game in America. I'm close to Mourinho apart from the tactical side," Mazzarri told Sport 360. "We both fight to do everything we can to bring benefits to our clubs in every way possible and this unites us. Every coach is an artist, and I see very similar to his way of viewing things."
Mazzarri bolstered his squad with the January signing of Hernanes from Lazio, and the Brazilian's arrival has coincided with an upturn in fortunes for the club.
Inter has won back to back games for the first time this year - including its first away win since November following Saturday's 2-1 victory against Fiorentina - and the 52-year-old was quick to compare his new recruit with another Serie A star.
"Hernanes, broadly speaking is like [Marek] Hamsik," he said. "His genius going forward will be so useful to the team, especially at home - he has maturity and qualities that will serve us well."
