Gio van Bronckhorst has hailed the Rangers substituties for changing the game in the narrow win over Aberdeen.
The Dutchman had been criticised for not looking to his bench in recent weeks, but brought on John Lundstram, Leon Balogun and Kemar Roofe against the Dons.
Roofe would go on to tap in the winner to ramp the pressure up on league leaders Celtic ahead of their clash with Livingston.
