Celtic have secured their place in the Scottish League Cup final after defeating Rangers 3-1 in extra time, marking their first derby victory under Martin O'Neill in over 20 years. The winning goals for Celtic were scored by Johnny Kenny, Callum McGregor, and Callum Osmond. Rangers were reduced to ten men for more than 80 minutes after Telo Aasgaard received a straight red card in the first half. O'Neill, who took over Celtic on an interim basis following Brendan Rodgers' unexpected resignation, now boasts 17 wins in 28 matches against Rangers.

The match began with Celtic in control, taking the lead through a Johnny Kenny goal in the 25th minute. After Aasgaard's dismissal, Rangers' hopes of a comeback dwindled, yet they managed to equalize with a James Tavernier penalty nine minutes before the end of regular time. However, in extra time, Celtic reasserted their dominance with goals from McGregor and Osmond, the latter scoring his first goal for the club.

Martin O'Neill expressed his satisfaction with the team's effort after the match, particularly praising young Osmond for his performance. O'Neill is uncertain whether he will lead the team in the final, scheduled for December 14 against St Mirren.

From a sporting perspective, Celtic have shown strong spirit and tactical flexibility under O'Neill's leadership, which could prove crucial in their pursuit of silverware this season.
