I say trainwreck, but I don't even mean this to hate on the guy, it's more the overall way this appontment is going. He's clearly able to get his teams to attack with power, combinative creativity, and intensity, but he just can't get the balance right. They seem overpowering, galloping ahead of themselves. He's to Nagelsmann what Bosz is to Ten Haag. Nagelsmann's Hoffenheim were similar in the CL though. And the performances against PSG surely weren't bad - but that's just it, isn't it. Always losing while getting good will points for 'spirited' performances
Then again, I've said it before, Marsch or no Marsch, RB Leipzig are done, we've finished them, you can thank us later. I wouldn't be surprised if we don't see them back in the CL anytime soon.
