Celtic came from behind to beat Old Firm rivals Rangers and move 19 points clear at the top of the Premiership.
Kenny Miller slid in to convert James Tavernier’s cross and put the home side ahead early on.
Moussa Dembele’s powerful shot from a Scott Sinclair corner flashed high into the net to bring Celtic level, and Dembele later fired against the bar.
The visitors dominated the second half, and Sinclair touched home Stuart Armstrong’s low cross for the winner.
Mark Warburton’s hosts showed from the outset their intention was to press their opponents in wide areas, and it paid dividends when Josh Windass released Tavernier to set up Miller’s close-range finish.
Celtic continued to concede too much space in the full-back areas, and further deliveries troubled goalkeeper Craig Gordon and his defence.
However, Dembele’s leveller put Celtic into the ascendancy and Rangers then struggled to get Barrie McKay and Tavernier on the ball, though McKay did draw a save from Gordon after the break.
Having struggled to get a telling delivery at set-pieces, Rangers may have gone ahead just before Celtic’s second as Danny Wilson met Tavernier’s corner, Gordon making the save.
Summer signings Dembele and Sinclair had run the Rangers defence ragged in September’s 5-1 win at Celtic Park, and the duo’s link-up play was again the catalyst as the visitors recovered from their early setback.
Sinclair’s set-piece was controlled and rattled into the top-right corner by Celtic’s top scorer Dembele – a fifth goal against Rangers for the Frenchman this season.
And he should have taken that tally to six after Mikael Lustig squared the ball to the striker early in the second period, a miskick allowing Wes Foderingham to save.
