Sterling, in particular, is revelling in this. He has had 159 touches in the opposition box so far this Premier League season - more than any other player. Guardiola knows that with his trickery in tight areas, getting Sterling on the ball in those situations will lead to goals.
He might not be the player with the most completed dribbles - Eden Hazard has 82 of them to Sterling's 38. But what matters is where on the pitch that Sterling is doing his dribbling. Note that it is he, not Hazard, who has completed more of them inside the opposition box.
