Jamie Carragher reckons his former side have already decided that their next big signing will be a centre-back, and mentioned their apparent interest in the Frenchman from the summer.
The former England defender has urged Jurgen Klopp and his staff to get a deal done for January 1, which could mean that they only have to play 11 fixtures without Virgil van Dijk before signing Upamecano.
That comes after Liverpool’s title credentials came into question after Van Dijk was ruled out for an extended period following a rash tackle from Jordan Pickford during the Merseyside derby.
While on Sky Sports, Carragher said: “Liverpool’s next big signing had to be centre-back anyway.
“And I’m talking next summer. (Dejan) Lovren went, they didn’t replace him in the squad, they’ve only got three centre-backs.
“One of them, (Joel) Matip, is always injured. And there’s question marks when speaking about (Joe) Gomez so there’s no doubt Liverpool have to go big in the transfer market next summer. That’s now got to be brought forward to January 1.
“Not the end of January, not negotiating with a club. There’s a young guy who everyone’s talking about, Upamecano at Leipzig, there’s talk of him.
“He’s not the profile of Van Dijk, maybe 6ft 1, 6ft 2, so he’s maybe not that aerial challenger, but if that’s the one Liverpool wanted next summer, bring it forward, pay extra money, and do it on January 1.
“That means Liverpool would have to get through the next 11 league games without Virgil van Dijk.”
Upamecano has proved to be a key player in the Bundesliga for RB Leipzig across the last four seasons, and even helped his side into the Champions League semi-finals last season.
Jermaine Jenas said after their win over Atletico Madrid: ”When you look at Upamecano going up against Diego Costa today, it was like no point Costa even being there.”

Van Dijk released a statement on his progress on Sunday, which reads: "This afternoon, I met with a leading consultant to start the process of planning the finer details of my rehabilitation following the incident yesterday.
“I’m now fully focused on my recovery and will do everything I can to be back as quickly as possible.
"Despite the obvious disappointment, I'm a firm believer that within difficulty lies opportunity and with God's help I'm going to make sure I return better, fitter and stronger than ever before.
"In football, as in life, I believe everything happens for a reason and it's important to try and keep level-headed whether going through the highs or the lows."
