Mehdi Taremi , the Iran captain, has claimed his players feel Fifa and the US authorities want them out of the World Cup.
Iran are set to find out later on Saturday if they have done enough to progress to the knockout stages for the first time in their history as one of the eight best third-placed teams.
A 1-1 draw against Egypt in the so-called Pride Match in Seattle , when Iran had a dramatic, stoppage-time winner ruled out by VAR for a razor-thin offside decision, left Amir Ghalenoei's side facing an anxious wait to discover if they have reached the last 32.
Taremi claimed after the game that Team Melli feel like the World Cup organisers do not want them in a tournament he described as a "disaster", as he criticised Gianni Infantino, the Fifa president, for doing "nothing" to help their cause.
Asked by Telegraph Sport if Iran felt it would be helpful to Fifa and the US authorities if they were not in the competition, the Olympiacos striker said: "We have to fight against everything here. I don't know if people want it or not, but as we see it by our perspective, yeah, they are like that I think."
Infantino visited the Iran dressing room after their opening 2-2 draw against New Zealand and said he would try to resolve the country's travel and logistical issues at the tournament. But Taremi accused Infantino and Fifa of failing to deliver on their promises.
"Infantino came to the first game and said, 'We will solve every problem here', but actually Fifa did nothing," Taremi said.
"Our logistics aren't here. We don't have our media. Where is our media? We can check it. No media here. No kit men, no vice-president, no president."

Ghalenoei, the Iran coach, also criticised their treatment at the hands of the US.
"What these young people, these players have done, it should be written in history, because the host country treated us very unfairly," Ghalenoei said. "Had the host country allowed us to arrive two weeks earlier, we would have been more prepared. They were reasonable, rational demands. We would have been able to recover and be in better shape physically and mentally. However, they deprived us of that justice.
"We have to return to Tijuana and it will take us some three hours. Their behaviour towards us has been really terrible and we hope the world will be aware of that."
After the game, Iran once again left another handwritten note in their dressing room, as they had done after their 0-0 draw against Belgium .
The note also contained the phrases "#168" and "#Minab", which are references to the number of people killed – most of them children – in a missile strike in Minab during the early stages of the US-Iran conflict. In addition #fairplay and the names of countries on whom Iran's hopes of reaching the last 32 rest were also referenced.
Iran were granted special dispensation to arrive two days early for their game against Egypt after complaining about their travel arrangements before their matches against New Zealand and Belgium, which ended in a 0-0 draw.
But Taremi said Iran were unhappy about being forced to fly back to their training base in Tijuana, Mexico , immediately after the Egypt match and the continued denial of visas to 11 staff, including Mehdi Taj, the Iran Football Federation president.
"We have to go back [to Tijuana]," he said. "We always complain about these things since the beginning. It's a disaster World Cup. A disaster.
"I mean Fifa have to solve every problem here, but unfortunately they couldn't solve [it] since the beginning. Mr Infantino came to our changing room after the first game, and he said it's just the beginning, but the group stage finishes tomorrow and we don't have our logistics people here. They don't have a visa.
"How is it possible we always have to travel to Tijuana? We love the people of Mexico, we love Tijuana. It's so good. But as professional players in a professional competition, it's not right. Now we have to travel again to Tijuana without recovery, without nothing, it's not fair.
"Who wants to help us? Who? If they want us to be out, OK let's get out. But that's not fair. We don't have recovery, we don't have any logistic people here to help us. What do we say? We always complain about these things. But no one helps. No one."

Taremi said Iran were "sad" that they did not manage to beat Egypt, and had a goal ruled out in stoppage time, but said they retained "hope" of making it through to the round of 32. "I feel sad but we have hope," he said. "If our dream becomes true, thank God. If not, I think we are proud of our game and our players because of how we did in the last three games. So let's see what happens."
To go through, Iran require one of the following scenarios to happen: Croatia to lose to Ghana in Group L; DR Congo fail to beat Uzbekistan in Group K, although Uzbekistan must not win by a seven-goal margin or better; either Algeria or Austria win their meeting in Group J.
Taremi missed a penalty before Ramin Rezaeian scored to cancel out Mahmoud Saber's fifth-minute goal. Iran thought they had won it in stoppage time but Shoja Khalilzadeh was ruled a fraction offside after turning home a goalmouth scramble. Saeid Ezatolahi then headed against the crossbar in the 97th minute.
"If anything happened [that sends us out], it's my responsibility because I missed the penalty. And if we pass the group stage, thank God," Taremi said.
Taremi said the logistical issues had affected performances on the field. "We complain about outside the football because those details are important," he said. "As you know, recovery is important and small details affect the football."
