The Reds pursued a deal for the Dutchman last summer, but were forced to publicly withdraw their interest after it emerged Jurgen Klopp had met the player before contact between the two clubs.
However, with Liverpool president Mike Gordon working to repair their relationship with the Saints in the closing months of 2017, they were able to enter negotiations.
City were also in the running to sign Van Dijk, but have lost out with the player’s preference to move to Merseyside.
The Times‘ Paul Joyce reports that an official announcement is due on Wednesday night:
Virgil van Dijk to Liverpool to be announced tonight. Undergone medical today. Joins on January 1.

And Jeremy Wilson writes that “personal terms of around £180,000-a-week are likely to be a formality.”
This would make Van Dijk the Reds’ highest-earning player, too, surpassing Philippe Coutinho, who signed a new £150,000-a-week contract back in January.
Moving swiftly to agree terms with Southampton serves as a major statement of intent from Klopp’ side, with the need to sign a new leading centre-back clear.
