Manchester City defender Ruben Dias says they'll be ready for Champions League opponents PSG this week.

City won their opening Champions League tie campaign with an extraordinary 6-3 victory against Leipzig in which £100million record signing Jack Grealish starred with a wonder goal.

"Jack is an outstanding talent," said Dias. "He has fitted into the changing room really well and been important for us at the start of the season.

"He has something that not many players have in terms of his vision and the ability to pick a pass, but also how he runs with the ball and takes on players.

"That makes him unpredictable for defenders. I'm sure he's going to be the difference for us a lot this season."
