The former Wolfsburg man, 26, has vowed to carry on doing the business.
He said: "Every time I see a paper, for what seems like a year or more there is a story saying that I am leaving City, or that I want to go.
"But I've never said that so the stories don't come from me. I've always wanted to stay at City and fight for my place.
"My motto has always been 'Never give up'.
"I hope the City fans who have always been fantastic towards me have seen I can score important goals for the team and that's what I want to carry on doing."
