Manchester City boss Pep Guardiola expects summer signing Rodri to improve upon his early displays.
Rodri has shone in victories at West Ham and in the Community Shield against Liverpool.
"Rodrigo has to play better, so does everyone," Guardiola said.
"He has potential as a young player, he's tall, but he's new. We have to see what we can do better.
"He's smart and he will get it. Like everyone, he can do better. "Everybody is fit including Fernandinho. Everybody deserves to play because the quality of the team is really good.
"We can talk about the line-ups but we have to think about what is best for the team and how to beat our opponent."
