The Ugandan international recently picked up the CAF Player of the Year (based in Africa) award, after a tremendous campaign at both club andnational team level.
Onyango was a influential figure between the sticks as The Brazilians marched to CAF Champions League glory, as he also inspired The Cranes to their first Africa Cup of Nations appearance in 39 years.
The towering shotstopper has now spoken for the first time about his achievement, since his crowning over a month ago, and feels honoured as a to have beaten stiff competition despite being a goalkeeper.
"Definitely I feel good, because it's not easy for a goalkeeper to beat players like Khama [Billiat] and also Rainford [Kalaba]," said Onyango after his club's training session on Thursday.
"But, all in all, the entire Africa has quality players and for me to scoop the award shows that I tried to do my best for my national team and my club.
"For me now it's all about focusing and looking forward to the next challenge, which is [to do well again] this year."
The former SuperSport United 'keeper admits he is currently in the best form of his career so far, and credits his period on the bench at 'Downs as a catalyst to his growth.
"Yes, everyone says a goalkeeper matures as he gets older, so I think for me it's that time of my career to show what I'm capable of doing," he added.
"I think it has paid off – sitting out for the past two or three years without having game-time. I think it was a lesson for me to wake up and fight hard for my position.
"[Last year] was fantastic and I'm really honoured to be part of a team like Sundowns that won almost everything – it was all dreams but now it has become a reality for me."
