The FAI have opened a 'Virtual Book of Condolence' where football supporters can express their sympathies to the family of the late Jack Charlton.
The Book of Condolence is now live at fai.ie/jack-charlton-rip
FAI President Gerry McAnaney said: "The national outpouring of grief since Jack's death was announced on Saturday morning has been phenomenal and reflective of the esteem in which Jack was held here in Ireland.
"We are offering Ireland fans the opportunity to extend their sympathies to Jack's family online and to show the family just how much Jack meant to all of us here in Ireland."
The Book of Condolence will remain live until Monday, 27 July when the FAI will share all messages with the Charlton family.
