The Ibrox manager took his side across Glasgow to Celtic Park earlier hoping to continue his strong start to life in management.
Going into the game, Rangers hadn’t lost so far this season and were in a particularly confident mood after qualifying for the Europa League group stages in midweek.
But they came off second best against Celtic, failing to cope with the quality of their rivals and it was Olivier Ntcham’s goal that gave the Hoops a well-earned victory.
It was a well-worked goal too, with the hosts breaking from deep in their own half before Ntcham fired home.
However, there was some debate about a possible Tom Rogic foul on Ryan Jack in the build-up.
Gerrard looked furious on the sideline that Collum didn’t give the foul – and he was clear in his blame of the referee while speaking post-match:
"It'd definitely a foul….it's actually a foul in the 4th official's book as well because he was shouting down the mic- 'foul, foul, foul'"
Gerrard frustrated a foul was not awarded to Ryan Jack in build-up to Celtic's winner. https://t.co/yo6Orezzm6

The incident looked soft, but there’s no doubt Rogic’s left leg connected with Jack.
But should it have been a foul?
