Johnstone believes other teams raise their game when playing the Gers.
The 132-goal hero said: “It just shows how difficult it is for Rangers, though. Livingston were bottom of the league before the game but, going on that performance, they shouldn't be anywhere near that if that is how they can play.
“When teams play Rangers, they give their all and rise to the occasion. If they played like they did against Rangers, they wouldn't be fighting for their lives at the bottom of the table.”
It was up to defender Marius Zaliukas to get Rangers back in the game after going one goal down, but Stuart McCall’s side could no clinch the victory against the side now 41 points below them in the table.
Livingston are favourites to get relegated to the third tier as of now, but the result was an impressive one. Rangers still moved into second place with the point, as it was their game in hand over Hibs, but a victory would have been much more appreciated at Ibrox.
Despite beating the likes of Hibs and Hearts in recent weeks - Hearts, who are 22 points ahead of them and have already won the title - Rangers have struggled against the lower sides in the table.
They could only secure a 2-2 draw with Alloa recently, whilst McCall’s first game in charge was a 1-1 draw with recent opponents Livingston.
There is a sense that their opponents are willing to try harder against Rangers, as, although not the force they once were, they are still a club with a history and reputation as one of Scotland’s greatest.
Defeating a club of Rangers’ stature would be impressive regardless of their current placing, and Johnstone has highlighted a problem that could really work against the Gers in the future.
