The Reds have spent almost £250m - including record fees for a defender and keeper - in the past 12 months but have not won a competition since the 2012 League Cup.
"First and foremost, my responsibility is for this club to be as successful as possible, and it's not about pushing through my thoughts on that and saying: "no, I don't want to buy players, and I don't want to pay big money" and stuff like that", Klopp said.
With Mohamed Salah, Roberto Firmino and Sadio Mane once again set to link up in attack the signings of Alisson, Keita and Fabinho will add some steel to the squad.
And three of the Reds' most talented youngsters will head out on loan to as they continue their development.
Liverpool last week completed the signing of Alisson from Roma for £65 million - the highest ever transfer fee for a goalkeeper.
But Liverpool made a decision to pass on the move and Alisson eventually signed with Serie A club Roma in February 2016 for just £6.7m. "That is true. But it is better to change your opinion than never have one". Was Virgil van Dijk worth £75m?
Liverpool has increased their pool of players not only by numbers but also with quality. The team look good and look sharp. Daniel Sturridge is back to fitness but we don't know how long that will last.
"I love that guy".
"I'm fine with him, 100 per cent". It's insane. The things he can do with the ball - he can defend, he can pass, he can dribble, he is fast, he is strong.
Lazar Markovic is wanted by clubs in Greece and Turkey while Middlesbrough, Wolfsburg and Reading have inquired about Ojo, the winger who is valued at £15m by the Merseysiders.
Has Klopp's summer spending finished?.
But Ward has since been sold to Leicester, meaning that Karius will nearly certainly be Klopp's second-choice goalkeeper for the coming season.
