Uruguayan Football Association, Ignacio Alonso says there is a good weather and confidence in camp to change the situation at the World Cup ahead of their clash with Ghana.
After two games in Group H, Uruguay have managed just a point after suffering defeat against Portugal on Monday afternoon.
Meanwhile, Ghana earned an important win to boost their chances of progressing to the round of 16.
The Black Stars inflicted a 3-2 win over the Asian giants to boost their chances of qualifying to the knockout phase.
The four-time African champions must avoid defeat against Uruguay to book a spot in the Round of 16.
Earlier reports suggested there was an unhealthy atmosphere in camp after defeat to Portugal but the FA boss has denied, saying there is an excellent atmosphere in camp.
He added there is an excellent atmosphere ahead of the Ghana game as they seek to reverse the situation.
"I totally deny it." He said.
"There are no inmates, I can assure and attest that there is an excellent climate," began by saying "Nachito" interviewed on Channel 12, and expanded: "There is discomfort over the result, pain, but good weather and confidence in the ability to reverse the situation".
"The performance is not what was expected," he said later, to complete: "It is not what is adjusted to the possibilities of this team, that is why there is also a great expectation of being able to turn the situation around."
The 2016 European champions are currently on the summit of Group H with six points, ahead of Ghana, who have three.
Meanwhile, Uruguay and South Korea both have one point each ahead of the final group games on Friday.
Ghana were denied a semifinal berth at the World Cup courtesy of a Luis Suarez handball incident in the quarterfinals of the 2010 World Cup in South Africa.
The former Liverpool and Barcelona forward prevent a goal-bound header from Ghana's Dominic Adiyiah in the final minute of extra time at the Soccer City Stadium in Johannesburg.
Suarez essentially produced a save on the line worthy of a goalkeeper and he was shown a straight red card as a result.
Ghana were also awarded a penalty, but Asamoah Gyan’s attempt from 12 yards crashed into the crossbar, which resulted in Suarez going mental on the touchline and sent the game to a shootout.
Uruguay won the penalty shoot-out to progress to the semifinals with Luis Suarez celebrated for his demonic act.
