Liverpool manager Jurgen Klopp insisted Liverpool remain in a "luxury position" in the transfer market amid frustration in some quarters over a lack of transfers.
The Reds have signed just backup left-back Kostas Tsimikas from Olympiacos this summer, prompting suggestions the club is choosing not to strengthen whilst at the top.
Speaking to Sky Sports ahead of Liverpool's opening Premier League clash against Leeds United, Klopp emphasised the club's sustainable approach to spending. However, he admitted the need to add "quantity" to the squad.
"Since I've been here, there's not been one transfer window where I thought if you don't get this player, then we can not start the season. Not one time," Klopp said.
"We are in a luxury situation, that if we can bring someone in who is a really good player, then that's good. If we don't bring someone in, then we still have really good players.
"This club, since I'm here and before, spend what we earn. That was always the case. I don't know why it's so surprising now - it's nothing new.
"We spend if we have to, if not, then we don't because it makes no sense. That's the situation.
"The only problem that we have is that we really need numbers as well. Definitely quality over quantity, but for this season, we need quantity as well, that's the truth.
"A season like this, no-one's done it before. Only two or three weeks where we play Sunday - Sunday, or Saturday - Saturday, it makes a massive difference. We do not have this.
"We play Saturday, Tuesday, Saturday or Sunday, Wednesday, etc. You don't train. You prepare and recover."
One area the Reds could find themselves short in is at centre-back. Following the departure of Dejan Lovren to Zenit St Petersburg, Klopp's has just three senior centre-backs to rely on for the upcoming season.
The likes of Sepp van den Berg, Ki-Jana Hoever and Billy Koumetio could be called upon following an impressive showing in pre-season. But Klopp admits defensive midfielder Fabinho could be moved into defence if need be, suggesting the boss is planning ahead without any further additions at the back.
"The situation is that we have a lot of centre-backs and all of them, apart from the three we used last year, are pretty young, which is good," Klopp said.
"There is a lot of space for development and all these kinds of things. They all did well, to be honest. Sepp did well in pre-season. Ki-Jana played at right-back but did well in pre-season.
"Billy did really well considering his age (of 17) especially. Nat Phillips came full of confidence back from Stuttgart, so that is all good.
"Fabinho can play as well. He did against Bayern in the Champions League once if I am right.
"Probably in another game as well (away at Brighton). It worked pretty well because he is a smart player.
"As always with a squad, you have to find a solution. You want to prepare for all possible problems in a season but you cannot. That is what we have to accept always, every year.
