Liverpool manager Arne Slot says the club are still looking to strengthen the squad before the transfer window closes.
The Reds tried to sign Martin Zubimendi from Real Sociedad but missed out after the Spain midfielder decided against the move.
It means Liverpool are the only Premier League side who have not made a major signing this summer, with the transfer window closing at 23:00 BST on Friday, 30 August.
"I've said many times already that our squad is really strong and it's not so easy to find players who can help us or even strengthen the squad," said Slot.
