Jurgen Klopp says he has "no real explanation" for Liverpool's lack of cutting edge after they slumped to a third defeat of the season with a 1-0 loss at Nottingham Forest.
Taiwo Awoniyi's second-half goal was enough for Steve Cooper's side at the City Ground on an afternoon when the visitors failed to create anything clear-cut in open play.
Virgil van Dijk had Liverpool's best two opportunities, heading wide from a set-piece situation at the end of the first half before his late effort from a corner into the box was well saved by Dean Henderson.
