Klopp questions why Liverpool are seen by many as City's only challengers.
The German said it’s only in England a club can "win the title in the transfer market".
Jurgen Klopp was happy with Liverpool's start to the new season but he has questioned why they are seen as Manchester City's main challengers for the Premier League title.
Klopp's Reds thumped West Ham 4-0 at Anfield on Sunday, as Sadio Mane’s brace, Mohamed Salah’s tap-in and Daniel Sturridge’s late goal handed the Merseyside club three points.
He told Sky Sports: "I couldn't be less interested in what other people say of us. We said it before the game again, what people say is sometimes nice, sometimes not so nice, but it is always not important.
"What is important is that we know what we want to be, and we want to be a challenger. How can we be something different? We didn't win anything in the last few years, that's the truth. And the other teams, I can't see that they've got weaker. So why should we [be the only challengers] because we made a few signings?
"It's only an English thing, where you can win the league in the transfer window. It's not possible. It's not interesting. We did our business, other teams did theirs last year, two years ago, whatever. We did it this year because we felt it was the right moment to do so, that's all! We enjoy our role, and all the rest is not important to us."
Regarding Liverpool's bright start to the new campaign, Klopp said everything went according to plan.
"You cannot wish for better. It was a fresh start from the first minute, everything looked like it should have been,” the former Dortmund boss said.
“It's a good day. It's only the start, and we know that, but for a start it was really good. We all know West Ham have a lot of quality, individual quality. In all other situations we were really concentrated defensively.
"It's a good game, now let's carry on. It's all good, but for the moment, it's no more. It's a nice moment, and we can enjoy it for two, three hours, and then prepare for Crystal Palace.
"We already today, with a few injuries, had to make really hard decisions. Alberto Moreno not in the squad, I have no explanation for that, apart from needing Clyney on the bench, or others on the bench.
"It's quite difficult to strengthen this squad, because this squad is good. They are used to the style of play, sometimes it needs a bit of time, I have no problem with that.
"Only the public and media could cause problems by questioning constantly why some aren't playing. We need everyone in that squad before the end of the season."
