We must keep Tevez - Johnson
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 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." Johnson believes playing in the Champions League will only enhance his own prospects of becoming a regular player with England. He said: "It's going to help me playing week-in, week-out in the Champions League, and doing well, and I will have a chance to be in most of the (England) squads. "Watching this season's final certainly whets your appetite to be involved in such things. "That's what you are in football for, Champions League finals, with the best players and the best teams in the world. "We are going to get the chance to do that next season." Johnson is pleased with the progress he has made since making the move from Middlesbrough to City 18 months ago, but he will be looking to improve his game further. He said: "When I signed, I knew I was joining something massive at City. "When I signed I had not played for England, or in the Champions League. But in the last year and a half since I signed, my whole life has changed. "I am always looking to improve. I scored seven goals this season and I want to try to add to that. "I also want to add to my assists, because that's the job of a winger, and try to get into double figures next season."
