The Al Duhail forward netted his fourth and fifth goals of the campaign during an entertaining first half as Qatar, who finished fourth at the competition’s 2016 edition, survived a late Palestinian rally to book a last four meeting with either Iraq or Vietnam.

However, despite Qatar moving to within 90 minutes of an appearance in the final, Ali is adamant that there is still plenty of hard work yet to come if Qatar are to claim the title.

“It is amazing that I was able to score two (more goals), and I want to say congratulations to my team because we played a very good game,” he said following the win.

“Qualifying for the semi-finals is very important for us, and we are very happy to reach this stage (of the tournament). However, I will still tell my team that we must continue working hard if we are to win the title.”

Qatar resolutely survived a late fightback from a resilient Palestine side, after Almoez Ali’s brace and Hashim Ali’s second half strike had put them in control of the last eight encounter in Changzhou.

While the victory helped set up a last four meeting with either Iraq or Vietnam, Sanchez believes it also underlined one of his squad’s key characteristics.

“I think these players have showed for the last four years that they are very competitive,” explained the Spaniard, who oversaw the Qatar side that finished fourth at the tournament’s 2016 edition.

“This group won the 2014 AFC U-19 Championship in Myanmar, and they reached the last four at the U23 Championship two years ago in Qatar.

“We are (once again) in the last four, while a lot of teams who came to win this competition are already out. We are also in the top four of Asia which for Qatar is, I believe, a very good achievement.

“But of course, we are going to fight very hard to go even further in this competition.”

The Al Duhail forward starred throughout an intriguing encounter to guide Qatar, who finished fourth at the competition’s 2016 edition, into the next phase and break Palestinian hearts after they had forced their way back into the game late on.

Qatar are now scheduled to meet either Iraq or Vietnam in the last four on Tuesday.

On a foggy night in Jiangsu province, it was tournament debutants Palestine who raced out of the blocks at the Changzhou Olympic Sports Center, striker Oday Dabbagh making the most of hesitancy in the Qatar defence to fizz a shot narrowly wide of the left-hand upright with only 40 seconds played.

Group A winners Qatar responded quickly however, and Felix Sanchez’s charges came close to taking the lead on seven minutes when Sultan Al Brake’s lobbed attempt from a quick Akram Afif free-kick landed on the roof of the net with Palestine goalkeeper Ramzi Fahkouri beaten.

Qatar continued to press their opponents, and after seeing Fakhouri make a fine save from his drilled shot, Almoez Ali finally broke the deadlock on 32 minutes, the livewire striker connecting with Bassam Al Rawi’s pinpoint pass to steer the ball home with an outstretched leg and claim his fourth goal of a memorable campaign.

Uzbekistan showcased a dominant display of football and raced to a comfortable three-goal lead in the first half, before Jasurbek Yakhshiboev sealed the win with his second goal of the game after the break.

Before the match began, both teams observed a minute’s silence in memory of the Uzbekistan citizens who perished in the recent bus fire in Kazakhstan.

Uzbekistan, well aware of Japan’s quality, applied pressure from the start and didn’t give the young Samurai Blue any space to move freely.

The early aggression gave Uzbekistan the lion’s share of possession, forcing Japan to play on the counter.
