"There would always be a point where we spent a bit more money". But that all made sense - we had to create a squad which is strong enough and wide enough to cope with the Premier League and to be as successful as possible.
With the transfer window still open in Italy, Spain, France and Germany, Klopp admits there could be further departures from Anfield.
But the German on Friday insisted they were still underdogs in the battle for the league crown, saying: "We are still Rocky Balboa and not Ivan Drago".
"We can not go there and win just because we are Liverpool".
In the Sylvester Stallone film the eponymous hero wins a 15th-round knockout against remorseless 100-win heavyweight Ivan Drago, who had previously killed Apollo Creed in a fight in which Balboa was in his fellow American's corner.
Alisson featured twice in pre-season for Liverpool, against Napoli and Torino.
"Step by step, we come closer". We want to be champions of England, but what about [Manchester] United and the other clubs?
"We have to be more consistent to be there and more clinical and aggressive in the right moments". We need to improve everything.
However, Klopp disagrees with that view as he pointed out that Manchester City, the defending champions, have strengthened significantly as well. We got the Champions League and that was a success, but we can only improve two more places without being champions.
"My own expectations are always pretty high: make the best out of it, get everything out of it, try to reach the highest", Klopp said.
