A hat-trick to Sara Shirbeigi and further goals from veteran Fahimeh Zarei and an own goal by Misato Komura sealed a outstanding victory for Sharhzad Mozafar’s side, who also won the inaugural title in Malaysia three years ago.

Japan had the better of goalless first half but failed to capitalise, before Iran produced a blistering scoring burst, that included three goals in two second-half minutes, to take the game away from Kenichiro Kogure’s side.

Masami Kato had two shots in the first six minutes, before Mika Eguchi forced Iranian goalkeeper Farzaneh Tavasoli into an excellent save six minutes later, and volleyed over the crossbar after tricking her way into space not long after.

The Iranians were magnificent in the final. Scoring five goals in the second half to blow Japan away with a 5-2 win.

It was their second successive title, but the first under Mozafar’s tutelage, and she shared her joy at taking her country to the top of the Asian women’s futsal mountain.

“I’m so happy at this moment. Actually, I’ve been waiting for this moment for many years,” she said.

“This is the best moment of my life.”

After producing a string of impressive displays and winning every match on the road to the decider, Iran’s performance on the final stage was their best in the eyes of their mentor.

“I think that was the best performance of our team,” she declared.

“The final is always a really unique match. The players are stressed and you have to control it, so I want to thank all of my assistants and staff.”

The 29-year-old delivered what could only be described as the perfect tournament in Bangkok, scoring five goals and, remarkably, winning player of the match honours in all five of Iran’s matches.

The scorer of the tournament-deciding goal in Malaysia three years ago, Karimi also left her mark on this year’s decider, playing a major role in Misato’s Komura’s 30th minute own goal, before setting up Sara Shirbeigi to make it 3-0 moments later.

Speaking moments after Iran’s sensational 5-2 win, Karimi spoke of the significance of lifting the trophy for a second time.

Thailand goalkeeper Pannipa Kamolrat was the eventual hero, saving Nguyen Thi Hue’s effort in the shootout, before Hataichanok Tappakun sealed victory with the decisive spot kick.

The result means Thailand retains the top three finishing position they achieved in the 2015 edition of the tournament in Malaysia.

In an opening period of few clear chances, Thailand largely controlled possession, but it took until the eighth minute for golden boot hopeful Sasicha Phothiwong to test goalkeeper Ngo Nguyen Thuy Linh.

Jenjira Bubpha dispossessed Bui Thi Trang to force the shot-stopper into another save four minutes later, but the hosts came the closest to breaking the first half deadlock when Bien Thi Hang intervened to clear the ball with Sasicha seemingly destined to steer the ball into the gaping net.

After a scoreless opening period, the breakthrough nearly came just 11 seconds after half-time, but Jenjira missed after being put through on goal by Sasicha.

Vietnam responded by creating a wonderful chance for Trinh Nguyen Thanh Hang five minutes later only for Pannipa to produce an important one-on-one save before her teammates arrive to help scramble the ball clear.
