For me is just surprising that almost every player from Borussia suffered many injuries during his time there, and almost everyone failed at other clubs.

And here, at Liverpool, everyone seems to be so good: let's talk about Salah. He was mediocre at Chelsea, now is one of the best in the world. Players like Trent, J. Gomez, Wijnaldum, Henderson, Robertson (just look at him running!) are obviously mediocre players, but they run out of their minds. Tbh, in the season when VVD was transferred to Liverpool, Southampton was nearly relegated, and he played half of the season there. Now he is invincible. I don't know, i might be wrong, but there are so many question marks behind Liverpool's success.
