Southampton officials claimed that Liverpool did not formally approach the club to request permission to speak to van Dijk. The club was notably provoked by what they see as an attempt to unsettle Van Dijk and are ready to reject an official offer.
The Saints were also adamant that they do not have to sell the player as Liverpool refused to comment on renewed speculation.
