After Rangers' opening-day draw at Motherwell, Russell Martin contended that what was undermining his team was "not really tactical, it's a mentality problem". Yet when he spoke following the haphazard 2-1 Europa League defeat on Thursday, there was a enervating familiarity about how the Rangers head coach explained away the outcome. "It's mentality, not a technical or tactical problem," Martin said. What unfolds on the pitch is predictable, while Martin's assessment has a sense of the inevitable about it too. So, for how much longer can Rangers and Martin work from the same script and wish for something different?
