As long as new contracts for Virgil van Dijk, Mohamed Salah and Trent Alexander-Arnold remain unsigned, they edge ever nearer to walking away as free agents.

The prospect of losing all three is an unthinkable one for a club whose charge towards a second league title in five years has been powered largely by the efforts of the trio.

Van Dijk and Salah, largely due to their respective ages of 33 and 32, are worth £23m and £46m, respectively.

As the website explains: "The Transfermarkt market values are calculated taking into account various pricing models.

A major factor is the Transfermarkt community, whose members discuss and evaluate player market values in detail.

In general, the Transfermarkt market values are not to be equated with transfer fees.

"The goal is not to predict a price but an expected value of a player in a free market.

It should be noted that in bigger leagues there is a heavier focus on transfer fees, while in smaller leagues where there is a greater emphasis on free transfers, the focus is primarily on salaries to determine market values.

"Our goal is to reflect the demand for the player and adjust for special factors/framework parameters in the medium term.

A player with an expiring contract has a transfer value of zero, the market value, however, is calculated independently from his actual transfer value."

So, to use their equation, Liverpool stand to see £131m worth of talent leave the club in Van Dijk, Salah and Alexander-Arnold before any money is invested in bringing in the sort of player that can cover the shortfall of quality and help Arne Slot succeed next season.

But if Liverpool are still determined to reach a scenario that sees all three stay put, Bayern Munich might provide some cause for optimism.
