The former Barcelona coach, who replaced Jupp Heynckes at the helm in the summer, has led the Bavarian club to the quarter-finals of the Champions League and semi-finals of the DFB-Pokal.
Munich also remain unbeaten in the Bundesliga under the 43-year-old, which Pizarro believes highlights his manager's greatness.
"I obviously knew about the titles he won at Barcelona and I heard a lot about him before he arrived. We knew we were getting a great coach," the former Chelsea player is quoted as saying by Goal.com.
"Now we've been working with him for nearly a year and we can see why he's so great. His philosophy of football, his system, the way he analyses opponents and the way he prepares us for games. The focused way he works is unique."
Bayern are in league action on Saturday when they face Mainz 05.
