“Dayot Upamecano from Leipzig, who is absolutely tremendous at the back – Leipzig won’t let him go,” Hamann said.
“I don’t think there is any chance whatsoever that [Liverpool] get a centre-back who will improve them for the next six weeks or next few years.
“I think [Upamecano] has a [release] clause [that would become active] in the summer. These clubs won’t sell [mid-season],” Hamann said bluntly.
“[Klopp] needs to see what he can get in January. You look at players who are not in the Champions League, maybe a bit lower down, and I’m not sure this is the type of player that Liverpool need to improve.
