Uruguay, who last won a World Cup game in 1990 against South Korea, earned a point with a dogged display in a goalless draw with France in Cape Town on Friday, and Tabarez said they would need to be much more aggressive in their next match.
"We do not have any added pressure at all," he told reporters at the pre-match news conference. "You could say we have our own natural pressure but it should not be excessive.
"Most of the players were little kids back then (in 1990). We cannot discus the causes of that (winless streak) because they run deep. We are all aware of this, players and coaches. But now we are in a position where we can change our record.
"In Uruguay there are great expectations."
"It is very difficult to communicate, it is impossible even in the warm up but when you play at the Maracana or at Boca's stadium you don't hear anything either," he said, in reference to the well-known Brazilian and Argentine stadiums.
"Perhaps using body language, especially for the players, may be a solution."
"It will be a beautiful match with a special atmosphere and we hope to give Uruguayans something to cheer about," he said.
