Despite both teams only needing a draw to progress, the U.S. boss has denied any claims his new side and old side will make a deal.
United States coach Jurgen Klinsmann rubbished suggestions he might do a deal with Germany to ensure both teams progress at the FIFA World Cup.
The USA looked set to secure a round of 16 berth on Sunday when it led 2-1 in second-half stoppage time against Portugal, but Silvestre Varela's very late header saw the match finish 2-2.
The result means both Germany and the USA are on four points ahead of their clash on Thursday, while Portugal and Ghana have a point each.
Germany and the USA could ensure they both advance with a draw, prompting questions at Klinsmann's post-match news conference in Manaus that he would approach compatriot and the German's coach Joachim Low to organize the result.
Low was Klinsmann's assistant when the latter led Germany to the semifinals of the 2006 World Cup in front of its home fans.
But Klinsmann rejected the idea of collusion completely, claiming it is against the Americans' nature.PHOTOS: Beautiful people in Brazil | Brazil protests | Soccer fanatics | Fan tattoos
"The U.S. is known to give all they have in every single game, otherwise Mexico wouldn't be here," he said.
In its final game of CONCACAF World Cup qualifying last year, the USA had already booked its ticket to Brazil when it traveled to Panama and trailed 2-1 late in the match.
That result could have seen the Panamanians advance ahead of the Americans' archrival Mexico.
Instead, Graham Zusi and Aron Johannsson both scored in additional time for the USA to secure a 3-2 victory, ending Panama's hopes and saving Mexico.
While it was Klinsmann's men who let in a late goal at the Arena Amazonia on Sunday, the 49-year-old coach did not hold back in praising his players.
"All of them fantastic," Klinsmann told ESPN. "They absolutely went to their limits but this is what it is now. In games like that, you have to prove your point and show your quality. You want to show the world that you're the best soccer players in the country.
"And that's what they're doing right now. They did an amazing job. We were that close. So we didn't make it quite yet. We have to make it against Germany."
