Portugal boss Paulo Bento concedes his nation is on the brink of World Cup elimination following their dramatic 2-2 draw with the USA in Manaus.
Only an injury-time equaliser from substitute Silvestre Varela prevented Portugal crashing out after two matches.
Nani opened the scoring during the early exchanges at the Arena Amazonia but goals from Jermaine Jones and USA captain Clint Dempsey turned the game around.
USA now just require a draw with Germany in their final Group G fixture for both of those teams to progress to the last 16 of the competition.
Bento told FIFA.com: "It's clearly not a good result for us. The 2-2 doesn't put us out of the World Cup mathematically, but it does leave us in a very difficult situation.
"Not just because of what we'll need to do against Ghana, but also because we'll need a favourable result from the Germany-United States game.
"We were unlucky late in the first half, but it was a great effort to level the match.
"Now all we can do is to give everything in our very last game and try and make the most of the very little chance that we have left."
