Celtic grind their way to glory
After 90 tense but mediocre minutes had failed to produce a goal, O’Dea, who had not scored since Celtic beat Livingston in February 2007, leapt to head a Shunsuke Nakamura free-kick past Allan McGregor in the first of the additional 30 minutes.
Then, in the dying seconds, Rangers defender Kirk Broadfoot was red-carded by referee Dougie McDonald for denying McGeady a clear goalscoring opportunity and the Republic of Ireland international scored from the spot.
