Suwon Bluewings coach Yoon Sung-hyo admits his side have to go for broke as they look to overturn a two-goal deficit at Al Sadd tomorrow night and reach the AFC Champions League final.
Two second-half goals from Mamadou Niang settled a fractious semi-final first-leg last week in Korea Republic, a game that was marred by a brawl in the closing stages which resulted in Suwon's Stevica Ristic and Al Sadd's Abdulakader Keita being sent off.
Niang was also dismissed in injury time after collecting a second yellow card, meaning all three are suspended for the clash at Sheik Jassim Bin Hamad Stadium.
"It is a must-win situation for us. We have to win and win big," said Yoon. "We have prepared well and are ready for the match. I hope this game is clean. We will be playing in difficult conditions. This is an away match and away matches are always difficult. We have played in such difficult situations before.
"Sometimes bad things can affect a team's preparation but we seem to be okay. We want to go to the final of the AFC Champions League and we can do that by winning tomorrow."
Al Sadd midfielder Wesam Rizik misses out through injury, while Mesaad Al Hamadi is a doubt with a broken nose, but Mohammed Kasola has shaken off the flu.
Despite starting heavy favourites, coach Jorge Fossati is refusing to take anything for granted, although the Uruguayan is confident of overcoming the Koreans.
"This is a very tough situation for us. Our players have been punished for other reasons. Of course, it has affected our preparation but let me tell you something, our level of football is not lesser than their level. Our level is better. We have better speed," Fossati said.
"We do not have a normal job but we are confident. I prefer to have a full squad but we cannot because of injuries and other issues. I said this before the first leg and I am saying it now. Any team that reaches the semi-finals of this important competition will have challenges to overcome. Ours is not an easy job but we will do our best."
Al Ittihad face tough task
Al Ittihad trail Jeonbuk Motors 3-2 ahead of their second leg at Jeonju World Cup Stadium but, coach Dimitri Davidovic is optimistic the Saudis can upset the odds against a side they knocked out at the same stage in 2004.
"Who would have thought that Manchester United would lose 6-1 at home to Manchester City? Nobody could have predicted that and it shows just how special a game football is and you can never say for sure what will happen," said the Belgian, who saw his side throw away a 2-1 lead in the first leg.
"There are always opportunities in sport and we are looking to put on a good performance. There is always a possibility and the possibility is there in this tie too."
Jeonbuk are set to be without Champions League top-scorer Lee Dong-gook. Lee was forced off towards the end of the first-half of last week's win in Jeddah and the former Middlesbrough striker is still struggling with a thigh strain.
Manager Choi Kang-hee is confident they can cover Lee's absence, though. "The likes of Jung Sung-hoon, Krunoslav Lovrek and Kim Dong-chan can come in and do a good job," he said. "It is not just about Lee being injured. We have a group of players who are up to the task."
