"We are still Rocky Balboa and not Ivan Drago", Klopp said. "That's all", Klopp insisted after Sunday's win. "We not only have nine new players, but three or four players who were not completely fit in pre-season", he added. How can we be something different? "We are the ones who have to do more and fight more - that must be our attitude".
But reunited at Liverpool they are set to take a big step forward, and the No. 10 was impressed with his new team-mate's first foray into life in the Premier League.
The Americans' renewed financial commitment on recruitment, following much soul-searching over sabremetrics on the back of Moneyball's success, has only intensified in recent years; evidenced by a spine which has not only broken the club's transfer record several times over in the past 12 months but also across multiple playing departments.
The game featured the debuts of Alisson Becker in goal, and Naby Keita in the midfield.
With Mo Salah virtually priced out of the market at just 4/11 (Sportsbook) to score and Roberto Firmino also too short at 8/11 given how little football he's played since the World Cup, the obvious goalscorer shout for Liverpool is Sadio Mane at 6/5.
The Reds finished in fourth place in successive seasons in the Premier League to ensure their continued participation in the Champions League in the 2018-19 campaign.
Mane's second should have been disallowed for offside but that was the only complaint West Ham could have about the result, with Manuel Pellegrini's expensively-assembled side looking a long way from settled.
Worryingly for the rest of the chasing pack, this Liverpool side is not the finished product. The squad has a tremendous amount of depth now with the likes of Jordan Henderson, Xherdan Shaqiri, and Daniel Sturridge coming off the bench today.
He said: "I came here to try to win titles".
"Obviously we've done work together as a unit, but it's not been hard either with the rest of the team".
"They think quickly [and] they have a very good understanding between themselves so my role is to support that, help in every way I can and hopefully provide them with some good service". They played better than us. When you lose 4-0 you can not have excuses. However, the Dutchman became started to make some sloppy errors in the second half - blazing a wild shot over the bar and making clumsy challenge or two when put under pressure.
One man who particularly disappointed was Marko Arnautovic, who had claimed he was ready to up his goal scoring tally this season.
