The Portuguese coach has been under the spotlight in recent times as Manchester United prepare to face Manchester City in a highly-anticipated derby encounter on Saturday.
Materazzi, who made 41 appearances for the Azzurri, believes there are five key factors that contribute most to Mourinho's success.
He told footballITALIA: "Drive, cleverness, knowledge, experience and empathy. Drive: he can multiply energies. We lost 3-1 against Catania and the next day he slaughtered us… four days later we go to London and beat Chelsea.
"Cleverness: He presses all the right buttons, not just his players. Knowledge, that's what he provides his team on the subject of their opponents,
"Experience: Mourinho knows how to win because he's done that a lot, and that in turn is because he started winning so early.
"Empathy: that's the first thing he seeks out with his team, the condition that is absolutely necessary to build a strong group, one that is united and has no cracks. That's what leads you to fight against everything and everyone."
