Newcastle, on Monday, confirmed Rafa Benitez has left the club.
The Magpies had hoped to tie Benitez down to a new contract with his current contract expiring this summer.
But talks have proven unsuccessful with Newcastle confirming he will depart on June 30.
The club statement said: “It is with disappointment that we announce manager Rafael BenÃtez will leave Newcastle United upon the expiry of his contract on 30th June 2019.
“We have worked hard to extend Rafa’s contract over a significant period of time, however, it has not been – and will not be – possible to reach an agreement with Rafa and his representatives.
“Rafa’s coaching staff, Paco de MÃguel Moreno, Antonio Gómez Pérez and Mikel Antia, will also leave the club on 30th June.
“We would like to thank Rafa and his coaching team for their efforts over the last three years and their significant contribution to what has been collectively achieved.
“We would also like to thank our supporters, players and staff for their patience during a period of uncertainty.
“The process to appoint a successor will now begin.”
