PORTO SEGURO, Brazil (AP) - Germany repeated its feat from four years ago by opening the World Cup with a 4-0 victory. Now it's hoping there won't be a repeat of its second game in South Africa when it takes on Ghana today.
The Germans routed Australia to start their 2010 campaign, but then lost to Serbia 1-0 in the next game.
After beating Portugal 4-0 on Monday in Brazil, Germany is wary of another letdown against Ghana - the same team it beat 1-0 in its third game in South Africa to reach the knockout round.
"The second match from four years ago is a warning," Germany defender Per Mertesacker said. "We opened very well, then lost. We'll have to take it very seriously."
Ghana lost its opening match 2-1 to the United States and can't afford another loss, while Germany would all but clinch a spot in the knockout rounds with another win.
A big downside from the opener, though, was an injury picked up by central defender Mats Hummels. A decision on his fitness won't be made until shortly before the match.
The rematch also brings together again the Boateng half-brothers, Jerome, a Germany defender, and Kevin-Prince, a forward for Ghana, who started on the bench against the United States. Regardless of whether he starts today, the Germans are quite familiar with their opponents.
"Ghana is a very physical team, they try to outplay you, they want to shine," Mertesacker said. "They are a dangerous team and we'll have to be very clever, especially in the heat. We'll have to play good defense."
Ghana team officials have denied reports of a "player revolt" against coach Kwesi Appiah following the loss to the United States.
Ghana's Joy FM said players - in particular Kevin-Prince Boateng, who plays for Schalke in Germany - were unhappy with Appiah's tactics in the defeat to the Americans. AC Milan's Michael Essien also started on the bench.
The radio station misinterpreted the reason why a news conference at the team base in Maceio was postponed Tuesday, the Ghana Football Association said, denying players had refused to report for the conference.
"We wish to state emphatically that the report is absolutely false and has no basis in fact," the GFA said. "There is no player revolt against the coach of Black Stars and no player or players have been involved in any mutiny in the wake of the 2-1 defeat to the United States."
