The Cameroon international is currently on a season-long loan at Trabzonspor.
He said: "I'm very happy, trust me. I'm living the best period of my life. I can't complain, I'm very happy to be here.
"Sometimes I'm driving and a car cuts in front of me. 'Onana, stop, I want a photo.' I think to myself, 'Yes, but we can do this in another way.' But when they see me, they're happy, and so am I. It was difficult at first, but now I understand.
"They are my men, I love them, and I love this feeling. Because they are very passionate. It's a wonderful thing. It's something you can't describe if you're not here. But the time I've spent here has been perfect for me. I'm happy to be here. It's a different lifestyle, but it's great. Truly incredible, amazing."
