Liverpool fell short of an unprecedented quadruple last season, faltering in both the Champions League final and on the last day of the Premier League season after lifting the Carabao Cup and FA Cup.
Liverpool relied on penalties in both of its cup successes as it failed to score in five and a half hours of football in major finals last season, which led to concerns over its ruthlessness in front of goal.
Darwin Nunez has since arrived at Anfield from Benfica in a deal reportedly worth £64million (€75m), with a further £21.4m in potential add-ons, in a move that Klopp will hope provides greater reliability in attack.
Star forward Mohamed Salah has also penned a contract extension and, despite Sadio Mane leaving for Bayern Munich, Klopp remains convinced Liverpool can compete with Manchester City once more.
"As confident as possible. You never know obviously but I saw today on the plane a squad full of quality," he said.
"You always need a little bit of luck, how we all know, if you want to win a trophy. But to play a good season you need first and foremost consistency, that's what it's all about and that's what we will try.
"I have no doubt about the quality of the boys. We brought in new players – yes, we lost a few players – but we brought in new players; if you want, fresh blood, really helpful.
"There are no places already sorted, who will play where. The boys will make pressure, which is important.
"We have five subs from now on in the Premier League as well – we have to get used to that, we have to adapt to that. I'm really looking forward to it.
"There are no guarantees in football but there's a good chance that we play another good season, I would say."
Liverpool faces fierce rival Manchester United in Bangkok on Wednesday in what will be Erik ten Hag's first game in charge of the Red Devils.
The Reds hammered United by an aggregate scoreline of 9-0 in the Premier League last season, and Klopp insists there will be no such thing as a friendly between the two teams.
"Manchester United, a new manager, trained a little bit longer than us so might be, I'm not sure, in a better situation in the moment," he added.
"But we see it as an important test because it's against United and we don't play friendlies, obviously both teams don't play friendlies against each other, so we will see what we can do.
"We never prepare for one match, we prepare for a full season. That means the boys who started Monday last week had a proper start so far, we could train in the way we wanted.
"We had now a full week already and we are now here to play two games in Asia, first this one and then in Singapore against Crystal Palace. So, we have to see.
"We have to train and we have to play, it means the games are actually like a session as well but the boys have to go really hard.
"Let's see where we stand in this specific moment and then we can go home to England and then we go from there to Austria for another camp."
