The issue of Liverpool is starting from the team, because the deficiency of their team poor performance i think that it's from the players, because if they want to perform well in this season, i think that they a midfielder and defender, at least they need to hire more players fir the team and sell the old performing players. So with that only you will see that the methods of Liverpool football style will change directly, so they performance is extremely low.
Another reason is strategy. I believe another coach in the premier league is very understood how Liverpool played, They can read the player movement on each line, this situation is the same as Chelsea before Tuchel. but, I don't say the Kloop strategy is already stale because when I look him on every match, he always improvement the player strategy, I think what can he do next is to do maximising Nunez and a bit forget about Salah.
I think Liverpool is currently facing the same problem as Chelsea before changing coaches. because the Liverpool players are actually quite good. However, the strategy they play does not match the style of play of the players themselves. It's the same as when Chelsea were coached by Tuchel. Chelsea have good players but a game strategy that doesn't match makes Chelsea look weak. but now that graham potter is the coach of chelsea then we can see the game and chelsea's performance is very good. even Chelsea was able to beat a strong team like Milan up to two times in a row in the champions league. I believe Liverpool will be better if they can change their game strategy.
