Liverpool boss Jurgen Klopp has dismissed concerns about the club's inactivity this summer.
There has been questions about Liverpool allowing their rivals to catch-up with them this summer.
Chelsea have signed Hakim Ziyech and Timo Werner - a former Klopp target - while Manchester United are expected to be busy.
But Klopp insists he will work with his Premier League champions, as well as talented group of youngsters.
"This squad... look at it," he said. "It is not a squad you have to change now and say 'OK, we need this position and this position'.
"If you are a football supporter, you still want a backup for him and him, of course. Even if you are completely happy with the first XI, you still want backups for everyone.
"We don't have a first XI, I'd say we have a first 16 or 17, where they can all play to the same level. But this is what we have to use, 100 per cent. And what we want to create are transfers internally."
He added: "So now we have the first glimpses of Neco Williams. He would not be here in this position if we were not convinced.
"All these boys, Curtis [Jones], Harvey [Elliott], Ki-Jana [Hoever], Sepp [van den Berg], Yasser [Larouci], Leighton [Clarkson], Jake [Cain], all these boys have done really well. And a few I don't know yet but I will know them soon.
We cannot spend millions and millions and millions because we think it is nice to do. We want to strengthen this squad, and this squad is strong. The problem with a strong squad is how do you improve a strong squad on the transfer market?
"It works with money, obviously. That is possible. But it never works only with money. You have to be creative and we try to be creative. We try to find solutions internally.
"There is still a lot to come. We have three or four players who can still make big, big steps, who are not in the first 12 or 13 so far. That is the pressure we make as well, internally.
"We have had these discussions throughout the last four-and-a-half years. You asked me if I will find solutions in the transfer market and you are right, we did that, 100 per cent. We did smart business, brought good players in and then did something on the training pitch, and that is not finished yet."
