ABU DHABI - A 21st minute goal by midfielder Mbenza Bedi gave TP Mazembe of DR Congo an upset 1-0 win over Mexico's Pachuca in their Club World Cup quarter-final on Friday. The African champions, who qualified for a semi-final meeting with Internacional of Brazil, notched their first victory in two appearances in the competition having lost twice in Abu Dhabi a year ago. Mazembe played with 10 men for the last nine minutes after their Zambian midfielder Stoppila Sunzu was sent off for a second yellow card offence. Concacaf champions Pachuca almost took the lead in the 19th minute when Argentine midfielder Alejandro Manso's shot from outside the box on the left hit the inside of the far post and crossed the front of goal before spinning out. Pachuca, in their third appearance in the competition, will play for fifth place against the losers of Saturday's quarter-final between Asian champions Seongnam of South Korea and the UAE's host team al-Wahda.
