To have a normal game, we need to have extended control/possession of the ball. Players like Bruno, Dalot, McT, Rashford, etc. do not allow for that, as risk taking is a nature of their game (Bruno, Rashford) or they are s*** (Dalot or McT).
It seems this is how ETH wants us to play, high risk quick transitions. Problem is we lose the ball too often, cannot win it quick enough like a Liverpool, cannot defend well when teams come at us and lose composure under any adversity.
So the answer to your question, we can have a normal game when we play a team like Palace's second team that can't be bothered as overcoming the issues above will take a lot of time, possibly more than a season.
