( CNN ) -- Asian champions Al Sadd have qualified for the semifinals of the Club World Cup after beating African champions Esperance of Tunisia 2-1 in Toyota , Japan , in a match marred by crowd trouble . Esperance fans repeatedly clashed with police and stewards , with one supporter also running onto the pitch before being dragged to the ground , after their side had two goals disallowed for offside , and penalty appeals rejected , in an enthraling match . Al Sadd 's victory , the fifth successive time the Asian champions have beaten their African equivalent in the tournament , means the Qatari side have secured a dream last four clash with European champions Barcelona on Thursday . Al Sadd went ahead in the 33rd minute when Khalfan Al Khalfan headed home a rebound after goalkeeper Moez Ben Cherifia failed to deal properly with Abdul Kader Keita 's long-range drive . And they doubeld their advantage four minutes after the break when Lee Jung-Soo headed a free-kick across goal for captain Abdullah Koni to knock in from close range . Both teams were making their debut in the competition , and Esperance gave themselves hope on the hour mark when Ousama Darragi headed home a set-piece . But , helped by a couple of contentious decisions , Al Sadd held on and will now pit their wits against tournament favorites Barcelona . Meanwhile , in the other fixture played on Sunday , Japanese champions Kashiwa Reysol beat CONCACAF champions Monterrey of Mexico on penalties , after their match had ended 1-1 . Ryohei Hayashi netted the winning spot-kick to see Kashiwa through 4-3 on penalties and seal a date with South American champions Santos of Brazil in the other semifinal on Wednesday .
