Southampton defender Virgil Van Dijk has handed in a formal transfer request.
The Holland international has been told that he will be fined two weeks’ wages by the Premier League club.
And that has proved to be the tipping point with the Dutchman formally informing the south coast side that he wants to make an exit.
Van Dijk has already verbally informed the Saints that he wants a transfer this Summer, but they have so far refused to let him leave.
A move to Anfield to join Liverpool remains the priority for the ex-Celtic man, but Southampton are not keen to do business with the Reds.
Chelsea remain very keen to sign the centre-back, while Manchester City are still monitoring his situation as well.
Whether Jurgen Klopp can pull off a deal will depend on how strongly Van Dijk wants to Liverpool rather than a rival.
It will also count on how determined Southampton are to avoid doing business with the club.
