The Reds are the only Premier League team yet to bring anyone in after their pursuit of Real Sociedad midfielder Martin Zubimendi was ended when the Spain international rejected a move to Anfield.
Centre-back Joel Matip, midfielder Thiago Alcantara and second-choice goalkeeper Adrian all left the club at the end of their contracts, while Fabio Carvalho was sold to Brentford in a £27.5million deal.
The departure of manager Jurgen Klopp after nine years at Anfield also represents a huge change for the club but Slot, who arrived from Feyenoord in June, is confident progress can be made with the quality of the squad he inherited.
