Former Liverpool midfielder David Thompson has called for the Reds to bring in another left-back and a physical striker before the transfer window slams shut.
Liverpool have made a profit on their summer transfer deals so far, being up to the tune of around £10m after shipping out players such as Brad Smith, Jordon Ibe, Joe Allen and Christian Benteke.
Jurgen Klopp's men went down to a 2-0 defeat to newly promoted Burnley at the weekend and came in for criticism for their defensive performance, with the back four now having shipped five goals in two Premier League games.
And Thompson, who does not want Klopp to panic buy, nevertheless feels the German must act.
He wrote on Twitter: "Klopp would be a fool to panic buy after Saturday (agreed) but you'd be a fool not to buy a left back and a striker of presence."

Liverpool are looking to push back into the top four this season and Klopp has the bonus of extra time to prepare his team for matches as the Reds are not involved in European competition in the current campaign.
On Saturday against Burnley, Liverpool had only three new signings involved in the game, in the shape of Ragnar Klavan, Marko Grujic (substitute) and Georginio Wijnaldum.
