Mexico's Pachuca fought back from two goals down to stun Egyptian side Al-Ahly 4-2 after extra time at the Club World Cup on Saturday. Argentine forward Christian Gimenez scored twice in a remarkable turnaround after Pachuca had trailed 2-0 at halftime as the Mexicans set up a semifinal with Ecuador's LDU. Pachuca meet South American champion LDU on Wednesday, 24 hours before tournament favorites Manchester United begin its quest to be crowned the world's best club side. “We didn't deserve to be two goals behind,” Pachuca coach Enrique Meza told reporters. “We were better than Al-Ahly in the first half and controlled the entire game. We kept attacking. It's the only way we know how to play. The better team won. It's a very simple logic. Now Bring on LDU.” Meza's side, who left the pitch in tears after losing to Tunisia's Etoile Sahel last year, finished the match to a chorus of “Oles!” from the crowd of 30,000 in Tokyo. Ahly had gone ahead through a Fausto Pinto own goal in the 28th minute and Angolan striker Flavio doubled their lead on the stroke of halftime. Luis Montes pulled one back for Pachuca two minutes after the break before Gimenez curled in a sweet free kick from 20 metres to equalise in the 73rd minute. Striker Damian Alvarez gave Pachuca the lead eight minutes into extra time with a sharp finish and Gimenez smashed home his side's fourth to seal victory. On Sunday, Adelaide will take on Gamba Osaka.
