Liverpool hero Steve Nicol has argued that Sergio Ramos is on the “wane” and the Reds would be seen as “desperate” if they moved for him in January.
Jurgen Klopp faces an injury crisis at the club as Liverpool are without the centre-back pairing of Joe Gomez and Virgil van Dijk.
And Liverpool have been linked with Manchester United target Dayot Upamecano and Napoli star Kalidou Koulibaly as they eye up alternative defensive options.
Ramos, who is widely considered as one of the best centre-backs in world football, has been heavily linked with Paris Saint-Germain in recent weeks as his contract continues to wind down.
Nicol, 58, believes that his former employers should be putting their full focus on signing RB Leipzig defender Upamecano over Real Madrid skipper Ramos.
When asked if Liverpool could benefit from Ramos in their current predicament, the former Reds defender told ESPN: “I don’t wish to make this sound bad, but it depends how desperate they are.
“Listen, if Virgil van Dijk has a setback and it’s going to take even longer, if Joe Gomez is struggling, you’d rather go for someone like Upamecano, at 21, who you’re going to have for a decade. It’s kind of a no-brainer.
“If you can’t get him, then you kind of start going down the list.
“Clearly, you want a younger player who is going to be there for some time. You really want to avoid stop-gaps, unless you’re in a real hole.
“So, listen, if they got Ramos it would only be for a couple of seasons. I think he’s on the wane a little.
“But it wouldn’t be the worst signing ever, he would do a job. But even he’s injured today, he did his hamstring.”
Liverpool will return to Premier League action on Sunday when they host Leicester City at Anfield.
