what did Chelsea do wrong against Liverpool?

Blazing blues yet again couldn't win 3 points against Liverpool fc. After a "not so" impressive start against Brighton, Chelsea have attracted the eyes of football pundits that where exactly Chelsea stands after spending 0.25 billion in the transfer market. Chelsea had only 2 crucial passes in the game against the champions and only managed to do 4 tackles in the match which is the lowest number of tackles in game week 2. Kai although had a great start at Carabao as he scored a hat trick, failed to impress the Chelsea fans in the previous match. The obvious question that is bothering all the fans that where did the money go?  with a new formation Lampard doesn't look set and he is unable to find a rhythm for his team. He can lament about his goal keeper's mistakes but he also knows that he shouldn't face the criticism alone. With rookie mistakes in defense to Mount's inability to find spaces behind, nothing went right for Lampard. Did he do a mistake by changing the game plan and why exactly Chelsea couldn't capitalize Liverpool's highline?
