Elano admits he's questioned himself this season after failing to nail down a regular start at Manchester City.
"There are times when I think I'm not useful anymore," he told The Guardian. "But behind all that, there is a good feeling about the City supporters and I respect that a lot.
"I feel they love me and I enjoy being part of this club. I just feel sad sometimes because I know what I can do and I helped to build a lot of things last year.
"I was the main scorer and did good things, but today I can say I changed my way of playing to serve the team.
"I want to be useful, but sometimes I feel left on the side.
"I will never change my behaviour towards my friends and I'm not saying bad things about the manager. He has the right to do whatever he wants.
"Yet it leaves me sad because I have my own targets and I'd like the manager to force me to do things because I'm the type who has the capacity to learn many things."
