Our passing isnt that good, but IMO this of letting the opposition having alot of the ball is a clear and deliberate tactic of Ranieri, to a certain degree. To lull them to being comfortable with possession, and then press hard and high up, and start the counter attacks. If you notice, quick turnover and attacks won high up are often how we score our goals, when they arent set pieces that is.
Go over our non-set pieces goals and you will notice this is something Ranieri aims for. Not have alot the ball, but when you do, be quick and direct with it.
