Filip Helander gave the Scottish champions a 1-0 win at Ibrox with a towering header, consigning their rivals to their worst start in the league since 1997/98.
Rangers were without key players likes James Tavernier and Allan McGregor, as well as Nathan Patterson and Jon McLaughlin but produced a solid performance with manager Steven Gerrard watching from home as he took isolated.
The win took Rangers on to nine points from 12 going into the international break with Celtic down in sixth with six points.

Rangers' most dangerous player in the first-half going close twice with long-range efforts. Was marshalled well by Ralston, however, but became a nuisance for Celtic when moved more centrally. Photo: Rob Casey - SNS Group

Worked hard for the team and engaged the Celtic centre-backs but didn't pose too much of a goal threat. Photo: Rob Casey - SNS Group
11. Alfredo Morelos - 7
Got better as the game went on having been quiet in the first half. One of those selfless performances in the final third, working for the team, putting himself about. Had a low effort saved by hart before going off. Photo: Alan Harvey - SNS Group
