David Silva says Manchester City captain Carlos Tevez is primed for a big performance against Manchester United.
Silva, 24, insists the striker is ready to be let off the leash again in the first league clash of the season between the two giants.
The Spanish international told The Sun: "Tevez is a worldwide star and is key for us. I think this derby match will be a hard test for Carlos but, now he is fully recovered from injury, he's going to offer a lot in what is certain to be a big spectacle.
"Our victory at West Brom on Sunday was very important for us with United in mind.
"The derby is a special day and we want to show our fans a new image after that 3-0 home defeat against Arsenal.
"People who recognise me in the street demand that we defeat United. So I know this derby is more that a just simple match, the atmosphere will be enormous.
"There is no clear favourite here but home advantage is very important to us.
"The players have spoken out in the dressing room and our objective is not to suffer another defeat in our own stadium. With this attitude we can aspire to win titles."
