So, the champions move three points clear at the top of the Premiership and claim the Glasgow bragging rights.
Celtic had more energy and were more clinical than Rangers, who huffed and puffed but could not fashion any meaningful chances against a back four that had been highlighted as a possible weak spot before kick off. However, the visitors were resolute throughout and well-organised at the back.
You can catch highlights of the game and all of yesterday's Premiership action on Sportscene at 19:15 on BBC Scotland.
Cheers for now.
