Manchester City boss Pep Guardiola wants to see more from Raheem Sterling despite his superb start to the season.
Sterling has gone from strength to strength under Guardiola in recent seasons, playing a pivotal role in City's consecutive Premier League title wins.
But Guardiola thinks the England international can take his game to another level after he scored in Tuesday's 2-0 win over Dinamo Zagreb.
"I said many times, in a few years he will be a better player than today," Guardiola said.
"His desire, the way he came in, he saw the first ball and attacked one against two. He was aggressive and the crowd said 'wow'.
"Raheem is a player who is always there. He has this talent. He loves to score goals. On the crosses you always have that feeling."
