Germany midfielder Bastian Schweinsteiger has accused World Cup quarterfinal rival Argentina of showing no respect for opponents and referees, and urged his teammates not to be provoked.
Germany eliminated Argentina on penalties four years ago at the same stage and there were chaotic scenes after the shootout with both sides exchanging punches and kicks in a fracas that included team officials from both benches.
"The shootout is still in our memory but what really weighs heavily on our minds is what happened after that match," Schweinsteiger said Wednesday. "We have to remain calm and not get provoked and I hope the referee will be very alert.
"You could see their behavior at halftime of the game against Mexico. When you look at their body language and gesticulation, they way they try to influence the referees, they have no respect. It's their mentality and character and we'll have to adjust."
Mexico and Argentina players had to be separated as they headed for the tunnel at halftime of the teams' second-round game, with the Mexicans furious over Argentina's first goal that came from an offside.
Argentina won 3-1.
Schweinsteiger also accused Argentine fans of taking the places of others in the stadiums and refusing to move. It was not clear where he had the evidence from.
But the Bayern Munich midfielder praised Argentina as a team, saying the squad coached by Diego Maradona was better in "every sector" than the team Germany beat four years ago.
Schweinsteiger singled out veteran Juan Sebastian Veron.
"He has played very strongly here, I have been impressed," Schweinsteiger said.
Schweinsteiger repeated that stopping Argentina star Lionel Messi will need a strong "collective effort."
"Other teams also have done it. He hasn't scored yet and we want to keep it that way," said Schweinsteiger, who has 78 games for Germany although he is still just 25.
"We'll find the right game plan to hurt Argentina, although we know how strong Argentina is. At this level, you can't make mistakes, it's the details that decide the match," he said.
Argentina beat Germany 1-0 with relative easy in a friendly in Munich in March but Schweinsteiger said that result meant little.
"One, it was a friendly. Two, they did not create many chances either. Three, we have gained a lot of confidence by beating England and the good tactics we used in that game," Schweinsteiger said. Germany advanced to the quarterfinal with a 4-1 win.
Schweinsteiger said he expected the upcoming match to be a tactical affair, "just as it was in 2006."
Argentina has only one win over Germany at the World Cup and that was when Maradona was still playing in 1986.
Both teams have a long World Cup history, having met five times and twice in the final.
Maradona led Argentina to a 3-2 win in Mexico, while four years later in Italy in 1990, Germany won 1-0 on a penalty. Those were also the last times either team won the World Cup.
Germany won a group match 3-1 in 1958 and the two teams drew 0-0 in another group match in 1966.
