He has been encouraged not just by his performances but by the fact that manager Pep Guardiola has used him more often than Aguero this season - including the Champions League game at Real Madrid where a Jesus header got the Blues back level on the scoresheet.
"Today Aguero is a little older and therefore he may not be able to do what I can do without the ball, which is to defend, steal the ball and help. I don't know if at 30 I'll be able to do that," he said in an Instagram Live.
"I have played important games, scored goals, I believe I am improving and I have more to improve. I feel that my greatest quality is my mindset."
