Vassell told City's website: "Ched set a great example straight away in training, he was shooting from everywhere and the goals were flying in for him. I didn't really know much about him, and I did not realise the power that he can strike the ball with.
"I hope that the fans get to see some of it this season, and the same with Daniel Sturridge. He's done well with England recently, he came into the first team last season and again the goals began to fly in for him.
"The competition is as strong as I have known it since I came to Manchester City and that should work well for us."
