In an interview with CardPlayer.com, Hamann said: "Keeping Virgil van Dijk has to be the priority for Liverpool, he is the heart of the team. He stabilizes everything and makes other players better. He's just a rock at the back and he's been for a number of years now, so I think he's the most important."
However, Hamann believes there remains a lack of clarity on whether Van Dijk has been offered a new deal or whether negotiations are ongoing. With just months left on several key contracts, including Mohamed Salah and Trent Alexander-Arnold, questions have been raised about Liverpool’s approach to contract renewals.
“It's a bizarre situation because we don't know whether he's been offered a contract or whether he's holding out for more money or what the situation is. So it's very hard to tell," he said.
“But I would find it very bizarre if these players hadn't been offered contracts. If they have been offered a contract you can't be too harsh on the club because the players might want more money or a longer deal so there is negotiation there.
“There's about 10 or 12 games to go and you don't know what's going to happen with them, when are you going to think about a replacement, it will be too late and that probably makes players more expensive. I'm sure they do their homework and that they've got players in mind, but it’s a very strange situation. Liverpool do their business differently to other teams and clubs – but you have to say that in the past and it hasn’t done too much harm.”
