I don't understand why some people in the fanbase care about saying how good E.Valverde was at Barcelona, actually the man played a miserable 4-4-2, without any speed on both wings and most of the time, he was outplayed by Messi who at that time was a midfielder/forward, changing his position as his dick wanted, nothing good could come out of this. That team was only consistent in the championship and that's it, at the lowest intensity of the opponent, they lost the match in the worst possible way.
However, Flick's mandate is still not up for judgment, because we don't know what he is capable of in the ko's ucl stages, so there is still time to wait. I also suspect now, that if he could beat some very big forces, several times, we will at least reach the UCL final, with Liverpool as the opponent, at least that's what I think.
