Moghanloo was previously the men's national coach, including at the 2015 World Championships in Chelyabinsk and 2016 Olympic Games at Rio de Janeiro.

Iran's men won three gold medals at the 2015 World Championships - more than any other nation.

A medal-free Olympics for Iran's men at Rio 2016 spelt the end for Moghanloo.

The 52-year-old is now back at the helm but has warned there is work to do.

"The current situation of our country in taekwondo in the adult age group is not good at all and this issue is quite obvious," Moghanloo told the state-run Islamic Republic News Agency.

"To start work, we divided the taekwondo practitioners into two groups, some of whom are Grand Prix [level] and others will participate in the first selection stage.

"As we approach the Asian Championships, these people will hold a selection with the Grand Prix taekwondo fighters to send the best people."

Chuncheon in South Korea is due to stage the Asian Championships this year, from June 24 to 27.

Hangzhou is scheduled to host the next major event on Moghanloo and Maddah's horizon, the Asian Games, with taekwondo scheduled from September 13 to 17, but with China's borders still largely shut doubt remains over whether or not the event will go ahead.

China has already had to give up the right to stage the World Championships this year because of the coronavirus pandemic, with Cancun now due to put on the event in November.

Twenty-one National Olympic Committees won taekwondo medals at the Tokyo 2020 Olympics, but Iran was not among them.

Iran won three medals at the 2019 World Championships in Manchester.
