Sky Sports sources understand that Liverpool have agreed a fee with Newcastle for Jose Enrique.
The 25-year-old has made it clear he does not want to extend his current contract at St James' Park, which has just one year left.
A number of clubs had been linked, but Liverpool were always reportedly in pole position and now they have made their move.
It is understood that a fee of £6million has been agreed between the two clubs and Enrique will now travel to Merseyside for a medical.
Newcastle will now be left hunting for a new left-back although they have already expressed an interest in PSV Eindhoven's Erik Pieters.
