The evergreen Brazilian was at his influential best during a magnificent campaign where City were just three victories short of winning every competition we were in.
Triumphs in the Premier League and Carabao Cup, plus reaching the Champions League final and FA Cup semi-final show just how close City came to creating history.
And the skipper says high standards on and off the pitch were key to an amazing campaign.
“I personally was proud because something that any footballer can do is to show your quality and show your value inside the pitch,” said Ferna.
“That was what I tried to do, every time I went to the pitch to play, I just wanted to show my quality and to show that I deserved to be here.
“I think I got it, I did it and this makes me very proud because after eight seasons, it's not easy at age 35, 36 to play at high level with the high intensity every three days.
“I did it and was so happy and I’m very proud about it.”
The Brazilian club legend says staying in Manchester and English life for another year will be a pleasure.
The 2021/22 will be his ninth in sky blue and he admits his family are very comfortable in the UK.
“I think Manchester and the UK in general can give you all those things, education, health care, and the tranquillity to live here the best way possible and for you to do your job as well," he said.
“That for sure was one of the things we put on the paper.
“It was, how can I say, a good point to decide to be here and to stay here another year.
“And for sure, my family are really happy. My son, he's starting to play football now. I hope he can follow his dad's path!”
