Pep Guardiola was impressed by Jack Grealish following Manchester City's 3-0 win against Aston Villa.

"He is incredible, incredible player, top player. I am happy for the fact he is an Aston Villa player and he got offers to move on but decided to stay there in the Championship ... He is a talented player -- fast in the final third, passes, always creates something," said Guardiola.

Guardiola added that his side must maintain their level of play as they chase Liverpool at the top of the table.

"I am not concerned about the table. I am concerned about the way we played. If we play the level we played in the second half, we can be there at the end of the season I am sure of that," said the City manager.
