Liverpool manager Brendan Rodgers confirmed the club are still working hard to bring in new faces before the closure of the transfer window on September 2.
The Reds have already made four signings this summer, but Rodgers is keen to add to his squad as the club look to get back in the top four of the English Premier League.
"There's a lot of work going on behind the scenes. Obviously it's not easy," Rodgers said.
"We have seen that from other clubs' experiences as well. But I'm confident we will add to the team. I don't think there is any doubt that we need that.
"The players that we've brought in have added great depth and support to the team, but I think for us now, that little bit of quality could really set us up for an exciting season.
"Everyone at the club, the recruitment team, the board and ourselves, we are all working hard to make that happen, and hopefully we can.
"There's money there available to get in the right types of players, but we don't want to panic and just bring in anyone. It has to be someone who can come in and improve the team."
While the Luis Suarez transfer saga might have overshadowed Liverpool's preseason preparations, one player has stood out with Philippe Coutinho showing his class time and again.
Rodgers admitted Coutinho's best position in the role behind the striker, but revealed playing the youngster in the hole would depend on the new signings that come in over the next three weeks.
"No question, Coutinho's best position is the No.10," Rodgers added.
"And once we get the right kind of quality to put on the sides, he will play in that central role. That is where he affects the game best.
"At the moment, he has the licence to jump in and come inside - joining in and making passes, and we accommodate defensively when he does that.
"But there is no doubt, his best position is in the middle."
