Ghana grabbed a 3-2 victory over Hungary to reach the final on Friday, when they will play the winners from Brazil and Costa Rica.
"There's no pressure at all," a smiling Tetteh told a press conference after the semi-final victory.
"We are one step from lifting the trophy and will be ready to play either Brazil or Costa Rica."
The Ghanaians are used to such games in this age group.
They have reached the final in 1993 and 2001 but lost both games against South American teams – Brazil and Argentina respectively.
Tetteh also said that the team's harmony will help them face any opponents.
"We have been playing a good football since the African Cup of Nations in Rwanda. Most of the players are here in Cairo so they enjoy consistency and continuity."
Dominic Adiyiah is Ghana's most lethal weapon so far, with the Fredrikstad striker scoring eight goals en route to final.
Captain Andre Ayew and striker Ransford Osei have been also impressing in the tournament.
"One or two players from this team will be with the seniors in the 2010 World Cup," Tetteh said, refusing to name those players.
"They will definitely be useful for the first team in South Africa."
