Defender Charlie Mulgrew admitted the spectre of the defeat by Ross County helped spur Celtic to the Scottish Cup final - even though he and most of his team-mates were not at the club for the loss.
Mulgrew was among eight of the starting line-up for the 4-0 semi-final win over Aberdeen who came to Celtic after the shock reverse last April.
But the centre-back, who opened the scoring four minutes after half-time, revealed manager Neil Lennon had warned his players of the dangers of failing to rise to the occasion again.
"It was fresh in a few boys' minds and definitely the manager's," Mulgrew said.
"He made it clear to us not to make the same mistakes again, have no regrets, and I think we did that."
