The 2009 Fifa Under-20 World Cup winner will be on the touchline for the Dansoman-based club when the 2012-13 Ghana Premier League season begins
He has been handed the Liberty Professionals job after veteran trainer, J.E Sarpong, was relieved of his duties on Friday.
Before this appointment, Tetteh served as the technical director of the Dansoman-based club. His return marks a third stint with the scientific soccer lads.
Tetteh is widely known for his feat in 2009 when he became the only coach to have led an African side to win the Fifa Under-20 World Cup after guiding Ghana’s Black Satellites to beat Brazil in the final in Egypt.
Meanwhile, Sarpong said he is not bothered about his exit.
“They told me I cannot be with them again due to financial challenges so the technical director [Sellas Tetteh] should take over,” Sarpong told Goal.com Ghana.
“I am used to this because it is part of the coaching job, but the only disappointment is that I was out of the country when the late Alhaji Sly Tetteh [bankroller of the club] called me to come and take over the job last year to help them escape relegation.”
Sarpong led the Accra-based Ghana Premier League side to finish 8th in the 2011-12 domestic top flight season and also reached the Round of 16 stage of the FA Cup.
