Liverpool is in bad shape right now I think their problem is Thiago in the midfield he only knows how to make tons of worthless passes without assist. But Klopp don't flop in big matches besides Tottenham are also struggling in the attacking department
I wouldn't criticize Thiago Alcantara so soon, he just recently moved to the EPL after a stellar time with German heavyweights Bayern Munich, he'll need time to adapt to the league as well as a new team/coache's strategy and imo, he hasn't been terrible since his move to anfield. Thiago is not the kind of midfielder renowned for assists, there are other things he brings to the game, he controls the midfield beautifully, his short passes creates spaces for others to move forward; I think Liverpool will see him at his best once the whole team starts playing better.
As for their game against Spurs, 'Mou also doesn't flop in big matches', that game has a draw written all over it.
