The win took the Uzbekistan side to 10 points, level with Saudi Arabia's Al Hilal SFC, who defeated Mumbai City 2-0.
Igor Gulban opened the scoring for the visitors just seven minutes into the match at the Azadi Stadium.
Navbahor doubled its lead with 21 minutes on the clock with some route-one play, when full-back Ibrokhimkhalil Yuldashev saw Ostun Urunov’s run and floated a long ball into his path, with the forward then making no mistake beating the keeper following a short run into the area before striking home.
Just two minutes had passed after the break when Uronov doubled his tally and added Navbahor’s third in the most aesthetically skillful ways, when Jamshid Iskanderov sent a ball his way above the defense, and Uronov somehow managed to catch it in the air with the back of his heel, just about changing its direction goalwards.
Mohammad Reza Azadi pulled a goal back in the 68th minute.
Navbahor will meet Al Hilal SFC at the end of the month at home in a game that could define the group, while Nassaji host Mumbai City FC at the same stadium.
