With three points from their opening two games in Group A, the hosts head into Wednesday’s crucial showdown with table-topping United Arab Emirates knowing that nothing less than a win will suffice if they are to realistically stand any chance of progressing to the next phase.

Given that the Emiratis have impressed during their victories over both Qatar and Chinese Taipei, Indonesia’s task is indeed a sizeable one, although Sjafri believes the host nation will lay everything on the line to secure the three points they so desperately crave.

“The struggle is not over yet,” he said.

On what proved to be a sensational night at Jakarta’s Gelora Bung Karno Stadium, Qatar made the most of several Indonesian defensive lapses to take a 4-1 lead into the half-time break and then extend their advantage with two more goals after the break.

Despite a subsequent Indonesian revival which saw them come within a whisker of taking a point, Sjafri was more than aware of the damage that had been done in the opening 45 minutes.

The Emiratis dominated proceedings from the first whistle as Ali Saleh, Majid Rashid and Rashed Mubarak all scored twice to cement the UAE’s position at the top of Group A and edge them closer to a place in the competition’s quarter-finals.

With a final fixture at this stage of the competition to come against hosts Indonesia on Wednesday, Batelli believes the margin of victory will only have a positive impact on the UAE youngsters.

Under normal circumstances, completing a hat-trick to put your team 6-1 up is a safe sign that three points have been safely secured, but Qatar's match against the hosts was anything but normal.

Umaru gave Bruno Pinheiro's side a seemingly insurmountable lead when he brought up their half-dozen, but four Indonesian goals in 16 minutes - including a hat-trick from substitute Todd Rivaldo Ferre - created pandemonium among the 38,000-strong crowd.

The Persipura Jayapura livewire scored a hat-trick and earned man of the match honours despite only entering the fray as a 55th-minute substitute, but still found himself on the losing side after a series of Indonesian defensive lapses in Sunday's Group A clash.

The host nation's loss means Wednesday's final opening round game against group leaders United Arab Emirates is one of vital importance, and Rivaldo Ferre said his side remains up for the challenge.

The talented 18-year-old midfielder followed up a consummate performance from Matchday One with yet another fine assist and two well-taken goals to help his side record their second successive victory and put them within touching distance of the next phase.

Having underlined their place at the top of the Group A table, the UAE could go through if host nation Indonesia beat Qatar in the day’s later game, but will definitely guarantee their progress should they get a point from their clash with the Indonesians on Wednesday.

Four goals within the opening 45 minutes set the tone on a night when Indonesia rallied magnificently late on but were left to rue a fragile defensive display which ultimately proved their undoing.

The result saw Qatar go second in Group A behind the United Arab Emirates - who they lost to on Matchday One - and left them knowing that a win against Chinese Taipei on Wednesday would give them every chance of progressing.
