Liverpool has played 11 games in the 2017/18 campaign so far, recording five wins, four draws, and two losses, with a goal difference of 21:19, which is a bit over 2.7 goals per contest on average.
Klopp's side played a frustrating 1-1 with Spartak Moscow in Russian Federation on Tuesday, and that could affect their preparations for the game on Sunday.
Liverpool have netted 12 goals in six games this season.
Only Paul Dummett (hamstring) and Massaidio Haidara (knee) are unavailable this weekend for Rafa Benitez who could field the same lineup as last weekend and continue to use Shelvey from the bench as an impact player if the Magpies find themselves needing a goal.
Newcastle will host Liverpool at 16:00 BST on Sunday 1 October at St James' Park. "I'm not interested in the criticism - it shouldn't have any effect", said Klopp, who has Sadio Mane back from suspension.
Which XI will Klopp pick for the game? Whether Benitez begins with either Joselu, Dwight Gayle or Aleksandar Mitrovic, none of them are likely to fill the opposition with dread.
Daniel Sturridge is the favourite to score at 7/5. That is nearly four goals per contest, so I expect to see three or four at St. James' Park on Sunday. However, Philippe Coutinho has scored two in two since his return, and he would be Reds' biggest threat against Newcastle.
Now at Newcastle, the former Liverpool manager has yet to taste defeat against Sunday's opponents at St James' Park. "We'll see what we do with them", he said.
No; Benitez's men must use their attacking assets against his former club, get speedsters DeAndre Yedlin and Christian Atsu running at the frail Liverpool back-line and look to win the game in a positive manner.
Jurgen Klopp also has only two injury concerns with long-term absentees Nathaniel Clyne (muscular) and Adam Lallana (thigh) inching closer to fitness but still unavailable.
