JOHANNESBURG (Reuters) - Carlos Tevez struck twice as Argentina set up a rematch of their 1986 and 1990 World Cup finals with Germany, beating Mexico 3-1 in their second round match in Soccer City on Sunday.
The Mexican players raised their arms in protest, coach Javier Aguirre appearing to point to the giant screen as his players berated Italian referee Roberto Rosetti who then went to his assistant linesman for confirmation.
Higuain's fourth goal of the tournament put him top of the goalscoring list.
It was all too much for Mexico whose substitutes had a heated exchange with their counterparts behind Aguirre's dugout at halftime.
There was no dispute, however, about Tevez's second, a stunning drive from 25-metres seven minutes into the second half.
Javier Hernandez pulled one back for Mexico on 71 minutes after a neat turn and powerful strike inside the area but it was to no avail.
"This was an important step, we're in the quarter finals and that's what matters, that we played well ... We need to rest and enjoy this victory, which wasn't easy against Mexico," Tevez said after the game.
Mexico coach Javier Aguirre said his team had lost its way following the controversial decision on Tevez's first goal.
"We got disorientated by the first goal, we lacked the mental strength and concentration to overcome the error that wasn't our own, and then we committed the second one," he told reporters after the game.
Aguirre said talented young players should, however, ensure a bright future for the team.
"We have a great generation of young players who must be put to the best possible use, I believe in four years they will be at the top," he said.
Argentina's win set up a quarter-final clash with Germany in Cape Town on Saturday.
