In the Celtic dressing room, there is experience of reeling off wins to secure a title.
Winning their last five league games nods to the defending champions’ ability to harness experience.
They might not have been challenged to the final day much before, but in contrast to Hearts their winning experience is considerable.
“I honestly do feel that Celtic will be calm, just because they’ve been in this situation so many times before,” Halliday said.
“Now, some people don’t think that counts for much. For me, I personally do.
“Hearts have felt the pressure of being the team that’s been hunted for 30 weeks consecutively now, and they’ve handled it already extremely well.
“You talk about a manager’s role, I’ve no doubt whatsoever that Derek McInnes has played a huge part in that.”
O’Dea also believes that however different players and managers handle these situations, neither Celtic nor Hearts, who have come from behind to take points in their last five games, have shown signs of toiling.
“Both teams have an abundance of character,” he said.
“I don’t know if I could pick a winner in terms of the character from both groups, they’ve both shown it, so it makes for a good ending.”
