Celtic boss Martin O'Neill said his side's wasteful finishing had cost them the SPL title after their heartbreaking last-gasp defeat to Motherwell.
The Bhoys were ahead with three minutes to go, but two Scott McDonald goals for Motherwell handed the title to Rangers.
"We had enough chances to win the game by six or seven goals and we always felt it would be difficult without the second goal," said O'Neill.
"We had unbelievable chances to get the second goal and spurned them all."
Celtic had to beat Motherwell to be sure of the title with Rangers winning their match against Hibs.
Chris Sutton's first-half strike looked to have done enough as the seconds ticked away, before McDonald's late intervention.
"It didn't matter if Motherwell got beaten 2-0 so they started to come forward," said O'Neill.
"We hadn't killed the game off and you pay the consequences.
"It's very painful and disappointing for the players. It's been a terrific effort right through the whole season and we've just come up short in the final game.
"But we'll come bouncing back, make no mistake about it. 2003 was a big disappointment and the team came roaring back.
"There's nothing to say to the players. They are absolutely gutted and it's a very disappointing day."
