<strong>Route to semi-final:</strong> Survived a scare in their Group F opener against underdogs Turkmenistan to <a href="https://www.thenational.ae/sport/football/hajime-moriyasu-warns-japan-they-must-raise-their-game-at-the-asian-cup-after-struggling-to-beat-turkmenistan-1.811227">eventually prevail 3-2</a>, then required a Genki Haraguchi penalty to get past an obdurate Oman before a battling 2-1 victory against Uzbekistan saw them advance as group winners. A sturdy defensive display <a href="https://www.thenational.ae/sport/football/takehiro-tomiyasu-goal-sends-saudi-arabia-packing-from-asian-cup-1.816126">against Saudi Arabia in the last 16</a> secured a fourth successive one-goal victory – a run that continued against Vietnam in the quarter-finals once Ritsu Doan's second-half penalty <a href="https://www.thenational.ae/sport/football/japan-reach-asian-cup-semi-finals-as-var-comes-into-play-for-first-time-in-tournament-1.817692">clinched a semi-final berth</a>. Yet to truly convince. <strong>Manager: </strong>Hajime Moriyasu – assistant to Akira Nishino before and at the 2018 World Cup before being promoted. Has had to deal with a host of injuries to key players, but has displayed tactical acumen throughout tournament. <strong>Star man: </strong>Takehiro Tomiyasu – plying his trade in Belgium with Sint-Truiden, the centre-back's reputation continues to rise with some accomplished performances. Aged 20, he is one of Asia's best defenders. <strong>What wins it:</strong> Moriyasu's tactical flexibility, despite a team in transition that lacks an elite striker. Technically proficient and, as the tournament's only four-time winners, have pedigree. <strong>Route to semi-final: </strong>Pre-tournament favourites, they <a href="https://www.thenational.ae/sport/football/yemen-suffer-disappointing-start-to-first-ever-asian-cup-campaign-1.810575">began with a 5-0 victory</a> against Yemen before <a href="https://www.thenational.ae/sport/football/iran-through-to-2019-asian-cup-last-16-after-2-0-win-over-vietnam-1.812337">defeating Vietnam 2-0</a> and then drawing with rivals Iraq in the group decider. The point was enough to secure top spot. <a href="https://www.thenational.ae/sport/football/oman-exit-2019-asian-cup-with-heads-held-high-after-last-16-defeat-to-iran-1.815873">Saw off Oman 2-0</a> in the last 16 thanks to two first-half goals, before providing arguably the tournament's best performance, when they swept aside Marcello Lippi's woeful <a href="https://www.thenational.ae/sport/football/iran-beat-china-in-abu-dhabi-to-reach-asian-cup-semi-finals-1.817760">China 3-0 in the quarters</a>. Yet to concede a goal through five matches. <strong>Manager:</strong> Carlos Queiroz – the highly respected Portuguese coach has been in charge since 2011, despite repeated clashes with his superiors and threats to stand down. Has allied a strong defence with stellar attacking talent. <strong>Star man:</strong> Sardar Azmoun – the Rubin Kazan striker announced his international retirement following criticism surrounding a poor 2018 World Cup, but returned in October. Has four goals in this tournament. <strong>What wins it:</strong> Delivering on their obvious prowess. Defensively sound, physically strong and disciplined, with a dangerous attack. Three-time winners, although last lifted trophy in 1976. <strong>Route to semi-final: </strong>Opened the tournament with a <a href="https://www.thenational.ae/sport/football/ahmed-khalil-uae-must-take-positives-from-draw-with-bahrain-in-asian-cup-opener-1.809752">draw against Bahrain</a>, but went on to top Group A following a <a href="https://www.thenational.ae/sport/football/uae-s-alberto-zaccheroni-delighted-to-give-fans-joy-from-asian-cup-win-over-india-1.811891">fortunate 2-0 win</a> against India and a draw with Thailand. Were made to sweat <a href="https://www.thenational.ae/sport/football/alberto-zaccheroni-praises-uae-s-strong-personality-in-reaching-asian-cup-quarter-finals-1.816308">against debutants Kyrgyzstan</a> in the last 16, needing an extra-time penalty from Ahmed Khalil to scrape through 3-2. Improved greatly in the <a href="https://www.thenational.ae/sport/football/alberto-zaccheroni-hails-uae-s-champion-character-after-reaching-asian-cup-semi-finals-1.818065">1-0 victory in the quarter-final</a> against defending champions Australia, nicking the match through Ali Mabkhout's 68th-minute winner. A second successive semi-final appearance. <strong>Manager: </strong>Alberto Zaccheroni – much-maligned throughout his 15-month reign and during the tournament's first four matches, but has earned plaudits for the display against Australia. Guided Japan to 2011 Asian Cup success. <strong>Star man:</strong> Ali Mabkhout – not been the best tournament overall for the 2015 Golden Boot winner, but still has four goals in five matches. Strike against Australia sealed the UAE's semi-final spot. <strong>What wins it: </strong>Another gargantuan defensive display, with the endeavour and spirit shown in the semi-final. Surviving mounting injury list. Home support could prove key as well. <strong>Route to semi-final: </strong>Built upon opening 2-0 victory against Lebanon with a <a href="https://www.thenational.ae/sport/football/almoez-ali-scores-four-as-qatar-thrash-north-korea-to-reach-2019-asian-cup-last-16-1.812721">resounding 6-0 triumph against North Korea</a>, which remains the greatest winning margin thus far this tournament. Clinched top spot in Group D by <a href="https://www.thenational.ae/sport/football/saudi-arabia-to-face-japan-in-last-16-of-asian-cup-after-qatar-loss-1.814875">getting past Saudi Arabia 2-0</a> in Abu Dhabi, before a narrow 1-0 victory in the last 16 against Iraq set up a quarter-final clash with South Korea. <a href="https://www.thenational.ae/sport/football/paulo-bento-blames-profligacy-for-south-korea-s-asian-cup-exit-to-qatar-1.818079">Defeated the two-time champions 1-0</a>, meaning they have yet to concede a goal in five matches. <strong>Manager:</strong> Felix Sanchez – the Spaniard has been based in Qatar for more than a decade, coaching at various age-group levels. Appointed to senior team in July 2017 and has put together a well-drilled side. <strong>Star man: </strong>Almoez Ali – difficult to look past the tournament's top scorer, although four of his seven goals came against North Korea and he has yet to find the net in the knockouts. A fast-developing forward, though. <strong>What wins it: </strong>Maintain their defensive shape, ride momentum from their somewhat surprising run to the semis, and Assim Madibo and Abdelkarim Hassan in particular continue to excel.
