The Iranian boss was clearly disappointed after their dramatic extra-time defeat, while Suwon\'s coach insisted his team can now reach the final of Asia\'s top club competition.Zob Ahan coach Mansour Ebrahimzadeh says Wednesday\'s 2-1 extra-time Asian Champions League (ACL) quarter-final second leg defeat to Suwon Bluewings was \"unbelievable\" and due to his side losing their discipline.The former Iran caretaker coach was clearly disappointed his side had bowed out 3-2 on aggregate to the Koreans, after claiming Zob Ahan edged the second leg on home turf.Mohammad Ghazi had put last season\'s beaten finalists ahead on 50 minutes, before Suwon rallied with Yang Sang-Min equalising on 77 minutes, before Mato Neretljak\'s extra-time winner from the spot.\"It was unbelievable how we lost the game today,\" Ebrahimzadeh told reporters after the game. \"A team who loses discipline and plays emotionally faces problems in the game like we did.\"He added: \"We lost the game on a day that we knew what we had to do. We tightened all the gaps, created many chances but came out losers.\"\"I told my players not to allow them to cross the ball, they turned out to be really dangerous on crosses.\" Ebrahimzadeh contined he felt his side were the better side on Wednesday evening, even after Ali Ahmadi was sent off in extra-time.\"They were better in Korea, I confess, but here we were the better team. We even created chances when we had one player less,\" he said.Suwon coach Yoon Sung-Hyo was delighted with the victory and said his team was capable of reaching the final with a clash against Qatari underdogs Al Sadd to come in the final four.\"For us, I don\'t care which team we face in the semis. We\'ve got sufficient self-confidence and abilities to make it to the final,\" Yoon told reporters.He added: \"In Korea, we had many chances but failed to convert them into goals. One reason was that we did not know enough about Zob Ahan.\"But today, we knew them better from the first leg and knew how to play for a win. My players put a lot of effort into the game for the win.\"
