But their hopes of a comeback were effectively extinguished when Mabouka was eventually dismissed for a unsafe challenge on Can, referee Wilmar Roldan first booking Siani and then producing a red card for the midfielder before reviewing the footage a second time on the protests of Cameroon players.
It took furious protests from the Cameroon players, including Siani sarcastically applauding Roldan, for the Colombian to check the monitor again and discover he had sent off the wrong player. They lost their opening game 2-0 against Copa America winners, Chile, before securing a point from the 1-1 draw against Australia in their second game.
Germany have won two of their three previous meetings with Cameroon and there was a 2-2 draw when the teams last met in a pre-World Cup friendly in 2014.
"It's the kind of team you want to play against because in some form or respect we want to emulate of their feats".
Head coach of Germany, Joachim Low, has warned his team that Cameroon are unsafe opponets, as they seek to qualify for the semi-final of the Confederations Cup on Sunday.
But Germany broke through after only two minutes of the second half when great skill from Julian Draxler enabled Kerem Demirbay to advance into space and rifle a powerful finish past Fabrice Ondoa from the edge of the box.
Cameroon fielded the same team for the third game in a row as midfielder Arnaud Djoum kept his place after Georges Mandjeck injured himself in the warm-up.
"But the boss said to me before the last World Cup, "why can't this be your best World Cup?" and funnily enough it was".
Against both Germany and Cameroon this week, Australia has conceded in the shadow of the half time interval.
"When you see how fast they play, what pace they have in their players in attack". "Our opponents played very well with a lot of aggression - perhaps too much in some cases". "I didn't come here to sightsee", Postecoglou said. We've made it hard for ourselves but nothing changes for us, we try to win every game we play, regardless of the opposition and the circumstances.
