Manchester City boss Roberto Mancini says Adam Johnson must start playing more for the team now that he is an England international.
The 23-year-old arrived at Eastlands in an initial £7m deal from Middlesbrough last season and immediately made an impression under Mancini.
Although the winger has yet to fully establish himself at the City of Manchester stadium, the youngster fitted in well when called upon by Fabio Capello.
Johnson scored in both Euro 2012 qualifiers against Bulgaria and Switzerland last month, and looks set for a long international career.
However, Mancini says Johnson must not get side-tracked by his new-found fame.
"Adam has to understand that sometimes it is important for a player to play for a team.
"He can have a top career if he understands that he must work and think about football every day, not about other things.
"I am very happy that he played for England but he needs to keep his feet on the ground.
"That is important, not just for Adam but for all young players.
"It is easy for a player like Adam, with a good attitude and good quality, to arrive at the top. But you must always stay there. You can never go back.
"Sometimes when players arrive at the top they think they have finished. Actually, you must work better than before."
