Moussa Dembele scored a late winner as Celtic beat Rangers 1-0 at Hampden to set up a Betfred Cup final against Aberdeen on November 27.
Erik Sviatchenko had a goal disallowed and Scott Sinclair saw his free-kick tipped on to the bar by the impressive Matt Gilks as Brendan Rodgers' side pressed.
The breakthrough came when Dembele netted his 14th goal of the season with just three minutes left after being teed up by substitute Leigh Griffiths.
