I like that Klopp is trying new things and tbf we are winning more games with the new formations but it doesn't look right. Maybe it's a response to the idea that teams have 'worked us out'. We're scoring more from moments of brilliance than well drilled discipline. I will take that but I would like to see cohesion and consistency.
I think it means impact each player has on the game. They probably use that Xg thingy ( whatever that is) to work it out.
I know what it's meant to mean, but like xG, I think it's a load of made-up nonsense. I know you don't like swearing, so I'll just say I think these things are a statistician's onanistic fantasy.
