Manchester City boss Pep Guardiola is delighted with the form of Jack Grealish.
The midfielder scored in victory at Arsenal in midweek.
Guardiola said, "Obviously he is playing really good. It is not just about his quality, but his ambition and aggression to beat people and attack the back line.
"The quality has always been there, but now he shows a commitment to taking a risk, but he has to continue.
"I am so pleased for everyone, but I want more. I still have the feeling that Kevin [de Bruyne] can do more and Jack [Grealish] can do more.
"They can do better - that would be the best word. I know the demand we will have ahead of us to the end of the season against tough and aggressive opponents. We need the players who have the feeling that we can do better."
