I don’t think you get some of these performances without having a decent amount of quality. Whether they are consistent enough to play like this without Klopp, who knows. But for their age, I don’t think you can just seemingly fit in with first team players without that quality.
So I think it’s a good sign to have so many young players look good enough to keep us in a title race, regardless of who the manager is.
We’ve had injuries kill other seasons under Klopp, after all.
