Irmatov, who showed a talent with the whistle after a teenage injury curtailed his playing ambitions, became a celebrity, appearing in television advertising campaigns and on billboards.
"He came to our university to present a football trophy and was surrounded," Kholov said. "Everyone wanted a photo with him and a ball that he autographed is now on display on the campus."
His fame reached its zenith after the 2014 World Cup, when he set a new tournament record. The 37-year-old has been in the middle for nine World Cup matches, more than any other referee in history.
"Hundreds of people were at the airport to greet him when he flew back home," Kholov said. "It was like a national hero had returned."
Uzbekistan's footballers have nowhere near the fame. Only a handful play outside Uzbekistan (mainly in Russia but also Ukraine, Serbia, South Korea and Kazakhstan) and the most high profile sportsman in recent times has been tennis player Dennis Istomin, who was ranked 33 in the world in 2012.
While their footballers may not be household names, they will be difficult opponents.
The White Wolves narrowly missed the final World Cup qualifying stage for Brazil (they were pipped by Jordan) and are ranked 51 in the world and third in Asia, ahead of Australia, South Korea and Iraq. The Uzbeks favour a passing game mixed with a direct approach, emphasising fast delivery to the strikers.
Many of their top players turn out for FC Bunyodkor in the Uzbek League, one of the wealthiest clubs in the region and champions for five of the past six seasons. At different times, they have been managed by Zico and Luiz Felipe Scolari, with the latter said to be the world's highest-paid manager at the time. Former World Cup winner Rivaldo also played there between 2008 and 2010.
The All Whites will encounter a busy city of more than two million during their brief stay in Tashkent.
It has the only subway system in Central Asia and a famous university but most of the historical landmarks were ruined by a 1966 earthquake.
