Qatar are through to the Asian Cup final for the first time in their history thanks to a 4-0 win over hosts United Arab Emirates, continuing their run of not conceding a single goal in the tournament.
UAE had the benefit of greater backing in the stands, yet on the pitch a well-organised Qatar made the most of their chances and then held firm at the back, as has been their plan throughout this year's competition.
Poor goalkeeping allowed Qatar to take the lead through Boualem Khoukhi, but their second was a moment of brilliance from tournament top-scorer Almoez Ali, who grabbed his eighth goal to extend his team's advantage.
Due to their desperate situation, UAE unsurprisingly spent most of the second half on top, but Qatar remained solid defensively and late goals from Hasan Al Haydos and Hamid Ismaeil emphatically booked their place in Friday's final with Japan.
The lively Qatar deservedly went ahead in the 22nd minute, when Boualem darted up the right flank and finished into the bottom-far corner from just inside the area, with goalkeeper Khalid Eisa Bilal allowing the ball to squirm beneath him.
Eisa was given little chance for Qatar's second, though, as Almoez sent a fine curling effort in off the bottom of the right-hand post with 37 minutes on the clock.
UAE began the second half with renewed urgency, forcing goalkeeper Saad Al Sheeb into action to keep out attempts from Ali Ahmed Mabkhout and Ahmed Khalil.
However, Qatar put the game beyond their opponents nine minutes from time - Hasan producing an exquisite dinked finish to beat Eisa when in the clear, with the goal followed by UAE fans throwing numerous bottles at the players as they celebrated.
Things got even worse for UAE in stoppage time, as Ismail Ahmed was shown a straight red for swinging an elbow into the face of Salem Al Hajri, while Hamid made it 4-0 soon after, netting on the break.
What does it mean? An historic final awaits
Whatever happens in Friday's final, history beckons for both teams. While Qatar will be aiming to win the Asian Cup for the first time, Japan are looking to claim an an unprecedented fifth title.
Almoez strikes again
One of the standout performers at the tournament, Almoez was influential once again on Tuesday. Not only did he add another to his impressive tally, but the goal itself was excellent. He was a little quieter after half-time as UAE pushed forward, though that should take nothing away from the prolific striker.
UAE rue Eisa slip-up
Although Qatar looked the better side early on, they did not properly threaten until their 22nd-minute goal, which Eisa was culpable for. His feeble attempt at a save saw the ball scramble under him, leaving UAE with an uphill struggle.
What's next?
Qatar head into the final to face record champions Japan, but it is the end of the line for UAE, with their involvement on home soil over.
