The Gers lost their previous match 3-2 against league leaders Celtic and many expected them to bounce back strongly against Kilmarnock.
However, Rangers failed to produce a strong performance despite enjoying a healthy 61% possession over the course of 90 minutes.
Popular football pundit Chris Sutton took to social networking site Twitter to express his reaction on the result.
Rangers were progressing smoothly under Graeme Murty and talks of a potential title challenge was being discussed, but following the two defeats such talks have dissipated.

Former Gers striker Kris Boyd scored against his old club to earn all three points for Kilmarnock.
