Clive Clarke has dismissed Roy Keane's insult over the weekend.
The former Sunderland defender was forced to retire, after collapsing during a game while on loan at Leicester in August 2007.
Ex-boss Keane rapped: "On a night we got beaten in the Cup by Luton, the staff came in and said 'Clive Clarke has had a heart attack at Leicester'.
"I said 'Is he OK? I'm shocked they found one. You could never tell by the way he plays'."
But 29-year-old Clarke's dad, Patrick, told The Sun last night that his son was not fussed by Keane's remarks.
He said: "Roy is Roy isn't he? I wouldn't worry about what he said and Clive isn't bothered about it either."
