Adam Johnson admits quiet man Carlos Tevez has given nothing away on his Manchester City future - but reckons the Argentinian is vital to the Blues' Champions League success.
Tevez once again has questions hanging over his future despite City boss Roberto Mancini declaring he was optimistic the striker would remain at Eastlands.
Johnson, currently preparing for England's Euro 2012 qualifier with Switzerland on Saturday, knows how crucial Tevez is if City are to build on their success of last season, when they finished third in the Barclays Premier League.
The 23-year-old winger said: "Carlos carries us sometimes with his goals and his drive.
"He is probably the best player I have played with.
"Some of the goals, and some of the stuff he does in training, is just unbelievable.
"Personally I hope we keep hold of him just like all the City fans do.
"He will be a major part next season when we are playing in the Champions League.
"He would be hard to replace. There are probably only five or six strikers out there who get you that many goals a season at the highest level.
"We have one of them, so it would be great if we could keep him."
Johnson explained that Tevez has given little away as to what his future plans may be, even to his team-mates.
He said: "Carlos does not really say much. He is quite quiet. He keeps himself to himself mostly.
"He does his talking on the pitch. That's what I like about him."
Meanwhile, Johnson has warned Manchester United that the Blues could soon become the leading club in the city.
The England and City winger acknowledges United's years of dominance but believes it "could all change" in the next 12 months.
City lifted the FA Cup and also qualified for the Champions League for the first time last season and are expected to embark on another spending spree this summer.
Johnson said: "United have been on top for decades now. But I think we are definitely closer.
"I think we are probably as close as we ever were. I think everyone knows that now.
"Maybe if you tweak the squad a little bit, we could give it a massive push next season, and who knows, it could all change."
