TASHKENT — Alibobo Rakhmatullaev's extra-time header sent Bunyodkor charging into the AFC Champions League semifinals Wednesday as he popped up to settle a pulsating 3-2 win over Adelaide United. The Uzbek champion twice hit back from a goal down to force extra-time at 2-2 and it was midfielder Rakhmatullaev who nodded the crucial goal, six minutes from a penalty shoot-out, for a 5-4 aggregate victory over two legs. Two weeks ago in Adelaide, the Central Asian side had fought back from a two-goal deficit to draw 2-2, and anyone expecting more fireworks at Tashkent's Jar Stadium was not to be disappointed. Fans were still arriving at the open-ended venue when Iain Ramsay, fed by Dario Vidosic at the top left corner of the box, rifled a diagonal shot across Bunyodkor keeper Ignatiy Nesterov to make it 1-0 in just the third minute. Bunyodkor immediately pressed for a reply and Adelaide's captain-goalkeeper Eugene Galekovic pulled out a fantastic double stop when he parried Jan Kozak's long-range effort and instinctively deflected Kamoliddin Murzoev's follow-up. But Bunyodkor was soon back on terms when its captain Viktor Karpenko's curling cross was met on the penalty spot by a leaping Lutfulla Turaev, who stretched to aim a glancing header into the bottom corner on 13 minutes. Adelaide remained under pressure and the talismanic Galekovic played hero when he twice stood up to one-on-one chances to Murzoev before half-time. The tie came roaring back to life on 63 minutes when Adelaide substitute Jeronimo Neumann squeezed a shot off Nesterov and over the line with one of his very first touches. Shortly afterward, Akmal Shorakhmedov swung at a loose ball in the box and connected with a volley that somehow squirmed through the diving Galekovic to level the game again at 2-2 on 72 minutes. Adelaide received another body-blow when midfielder Fabian Barbiero was sent off for his second yellow card after a lazy challenge on Rakhmatullaev. But Bunyodkor was also reduced to 10 men after the first 10 minutes of extra time. Both sides were subdued in the tense closing stages but with six minutes to go, Turaev's probing cross found Rakhmatullaev on the far post and he planted his header past Galekovic for the winning goal, sparking wild celebrations. In the semifinals, Bunyodkor will face either Saudi side Al-Hilal or South Korea's Ulsan Hyundai, who were playing later Wednesday with Ulsan holding a 1-0 advantage from the first leg. Saudi Arabia's two-time AFC Champions League winner Al-Ittihad will play cross-Jeddah rival Al-Ahli in the other two-leg semifinal, starting on Oct. 22. A first-half brace from Amad Al-Hosni helped Ahli reach the semifinals Tuesday with a 4-1 win over easing past 10-man Sepahan of Iran. — Agencies
