Argentina defender Martin Demichelis has inflamed the war of words ahead of Saturday's World Cup quarter-final with Germany by declaring: "Show us some respect."
Ill-feeling between the sides who will meet in Cape Town for a place in the last four and a clash with either Spain or Paraguay was initially triggered by Bastian Schweinsteiger. The growing resentment continued on both sides on Thursday, putting Demichelis in a tricky position as a key member of both the Argentina defence and Bayern Munich.
But he does feel the Germans are going too far. "I have been in Germany for seven years," said Demichelis. "They know me and they know I won't change. But it does seem they Germany don't have a lot of respect for us."
He added: "I am not paying much attention to it, but maybe they should show us some respect."
Schweinsteiger claimed Argentina try to provoke their opponents and whinge at referees.
The South Americans are clearly unhappy, although neither German general manager Oliver Bierhoff, nor skipper Phillip Lahm saw any need to apologise.
"I played with a lot of people from Argentina," said Bierhoff. "They are hospitable, friendly people.
"But that is not necessarily the case on a football pitch, where they can be a passionate, aggressive, provocative side.
"I didn't think four years ago was particularly physical or nasty, but it is always tragic to lose on penalties like that.
"What we have to do on Saturday is keep a level head and make sure our nerves are in check."
