A revelation in his first season at Anfield with 44 goals in all competitions, Salah is now a marked man. Given their slip-ups against lesser teams last season, this result also serves as a statement of intent from the Reds in their efforts to rectify that shortcoming.
The German said: "We know about our expectations and we realise there is a really positive atmosphere around us in the pre-season. That's all", Klopp insisted after Sunday's win. After last season's painful and horrid ending to a fairy tale Champions League run you'd think it would be hard for them to recover from such a heartbreaking end. "But I can not say now "we will not go there" because my job is to make Liverpool as strong as possible".
"So we have to invest more, we have to fight more, we have to create more". Another mid-table finish is probably the ceiling West Ham can expect this season, but a Europa League qualifying spot could be possible if they get on a hot start. So those teams will have work their way into City's thoughts. "After six weeks in I don't make the difference between a new player and another player because for me, it is exactly similar importance that Millie [James Milner] and Gini [Wijnaldum] are ready to make the next step in their development as well".
Speaking of the defensive situation ahead of the game, the Liverpool manager said in his pre-match press conference, "Dejan will not be available for the weekend, that's how it is". The only visceral tones now are reserved for opposing players and match officials.
Goalkeeper Alisson will aim to hoist the Liverpool defence wearing the No.13 this season after joining from Roma for a renowned fee of £67m.
Klopp believes they still have improvements to make after a four-goal show that had Anfield dreaming big already.
Yet, he was given the simplest of tasks to tap home the opener into an empty net on 19 minutes from Andy Robertson's pinpoint cross after he was freed down the left by the impressive Keita.
That's great to see for Liverpool fans, whose last real memory of him was coming off injured in the Champions League final.
Sadio Mane also continued his fine form for the Reds, scoring twice.
Worryingly for the rest of the chasing pack, this Liverpool side is not the finished product. But his much-changed Hammers side were never going to have enough to nullify European football's most potent attacking triumvirate.
"People are not feeling that way about Manchester United or Tottenham or Chelsea at this moment in time, because of what has happened in pre-season".
And despite previously admitting his destain for the modern day transfers in the Premier League, Klopp knows he must move with the times.
"Liverpool deserved to win". They played better than us.
Liverpool won the game 4-0. "This is why we have a chance and why we look forward to giving all we have from now until the last kick of the last game". They had a lot of confidence to play with the score of 3-0.
At the same time, I think many of us are wary of the time it may take for our players to gel and for Pellegrini's style of play to be instilled into our side. "That's the expectations. Ours is the highest but we know that".
