Since Mamelodi Sundowns star Denis Onyango retired from international football and later came back, Watenga has been mainly Uganda's number one goalkeeper.
He was key as the CECAFA heavyweights fought and qualified for the 2025 African Cup of Nations finals set to be held in Morocco.
Although he was a regular starter, Watenga came under a negative spotlight during a qualifying match against Mozambique in March this year, when his mistakes led to a 3-1 defeat by Mozambique at the Cairo International Stadium in Egypt.
His three mistakes led to the three goals that Uganda conceded, and he was substituted at half-time.
