Kelleher played for Ringmahon in Ireland before leaving for the Reds as a teen.
“It is all a bit surreal watching him at that level," Harrington told the Sunday World.
“When I see him, I am buzzing and nervous for him, too. I travelled over to watch his Liverpool debut against MK Dons in the Carabao Cup (in 2019). He has been around the squad for three or four years now and is used to that level.
“It is great for Ringmahon, too. There are three former players in England now – Alan Browne and Adam O'Reilly are both at Preston. Alan and Caoimhín are from the same parish and have both made it into the Irish squad. It's an amazing story and achievement."
