Ngomna began playing football with Cotonsport Garoua, and made his Elite One debut during a one-year spell at Espérance Guider. He would return to Cotonsport where he played for 8 seasons in Elite One.[1]
Ngomna played recently for Cameroonian side Cotonsport Garoua,[2] and Sur Club in Oman.[3]
With Cotonsport, Ngomna captained the club to the 2003 CAF Cup Final and the 2008 CAF Champions League Final.[4][5][6] After the club's success in the 2008 CAF Champions League, Ngomna was one of several star players who looked for a transfer to a professional club abroad, but returned to Cotonsport without finalizing a transfer,[7] going on to play in the 2009 CAF Champions League.[8]
Ngomna ultimately secured a move to Omani side Sur Club, where he helped the club win the 2010–11 Oman First Division League championship, scoring as Sur won the final on penalties.[9]
Ngomna played for Al-Kahrabaa FC in the Iraqi Premier League during the 2014–15 season.[10]
Ngomna's older brother, Bouba, is a journalist for a Yaoundé radio station, leading to speculation that Ngomna wasn't selected for the Cameroon national football team due to his brother's criticism of the sports minister.[11]
