The innovative system was implemented at the 2019 AFC Champions League’s Group C match between Qatar’s Al Duhail and the UAE’s Al Ain, which ended in a 2-2 draw at the Al Duhail Stadium, in the presence of QSL CEO Hani Taleb Ballan and with the backing of Ahmed Khellil Abbassi, Executive Director of Competition and Football Development (Acting) at QSL.

The Asian Football Confederation gave approval for the system to be implemented in two matches. It will also be used during the AFC Champions League Group B match between Qatar’s Al Rayyan and the UAE’s Al Wahda at the Al Sadd Stadium on Tuesday.

Melbourne have endured a disappointing start to their Group F campaign, losing successive games to Korea Republic’s Daegu FC and Japan’s Sanfrecce Hiroshima to leave them propping up the table, three points behind two-time champions Guangzhou and six off top spot.

The Australian side have struggled on the road over the years in the AFC Champions League and have yet to record a victory in 20 attempts, meaning three points at Tianhe Stadium would be regarded as a huge turn up for the books.

The 2017 AFC Champions League finalists came from two goals down inside the first half an hour to rescue their second point in the continental campaign.

For a second consecutive AFC Champions League tie, Zobahan conceded early only to rebound in impressive style to secure victory.

Caio's 14th minute opener at Al Wasl Stadium wasn't quite as quick as the goal Al Nassr's Giuliano netted to put Zobahan behind on Matchday Two, but the Isfahan side needed just two minutes to restore parity through Christian Osaguona before adding further goals from Amir Motahari and Hamid Bou Hamdan.

A recent poor run that included a defeat to bitter rivals Persepolis was not the ideal preparation for a difficult-looking Group C clash against Saudi Arabia powerhouse Al Hilal, but Tehran giants Esteghlal rose to the occasion to secure a priceless win - their first of the 2019 edition - and stay in contention in the race for the Round 16.

Following more than 370,000 votes in total, with 16 entries from the inaugural campaign up till as recently as last year, the fans' favourite was decided: Iranian icon Teymourian's breathtaking goal from Esteghlal's quarter-final second leg against Thailand's Buriram United.

Al Sadd sealed the QSL title - their first since the 2012-13 season - with a match to spare after defending champions Al Duhail lost 1-0 to Kharaitiyat. The win gave Al Sadd an unassailable 54 points from 21 matches with Al Duhail on 47.
