Liverpool great John Aldridge insists manager Jurgen Klopp still needs to buy a centre-half in January.
He wrote for the Sunday World: "I have been suggesting for several weeks in my Sunday World columns that Liverpool need to be bold in the transfer market in January and get a defender in to plug the gap left by Virgil van Dijk and Joe Gomez's injuries.
"The displays put in by the team in the last few weeks may inspire the club to believe they can save £20-30million in the transfer market next month and still win the title.
"Rhys Williams and Nat Phillips have done a fantastic job filling in at the heart of the defence and Klopp has been singing their praises as a result.
"Williams was impressive as he kept Harry Kane quiet on Wednesday bight, but I would still have some concerns that they could get caught out over the course of a long season.
"Liverpool have some great young players on the bench right now, but Klopp would not want to be playing too many of them in the same team too often at this formative stage of their development.
"With that in mind, I would still be tempted to buy a defender in January, as that one quality investment could be the final piece of the jigsaw that pushes Liverpool over the winning line in the title race."
