I agree that when it went well it could be brilliant to watch. But the frustration lies in when its 0-0 or you are 1 down and time is running out yet the team are still passing sideways and back.
For me Russball depends far too much on how comfortable your players, defenders in particular, are on the ball. Problem is as you get lower down the pyramid they become less and less comfortable. Leicester should have enough quality even after selling some to get back up, but I dont think it will be plain sailing and without Russball causing more than a few frustrations along the way.
