Grealish was a constant nuisance for the Chelsea defence and forced Edouard Mendy into multiple smart saves.
The attacker had the most shots in the game (6), the most touches inside the Chelsea box (9) and was named as the Player of the Match after a standout display at the Etihad Stadium that had everything but a goal.
Goals from Riyad Mahrez and Julian Alvarez secured the win, but Phillips was in awe of his the Grealish display. He said:
"Jack [Grealish] has trained hard every single day.
"He's not had the luck with scoring and assists, but I think he brings a lot more to the team than just that.
"When you see him play and he plays like that, it's a joy to watch."
