It’s absolutely this.
Since mid Feb they have only beaten St Mirren & Motherwell in the league without a goal in the last few minutes.
Killie, Hearts & Dundee were all injury time winners then the goal against us was pretty late.
In the same period we’ve dropped points against St Johnstone, Kilmarnock & Hibs - all games we should have won but been unable to. Then a calamity defensively to gift celtic the win against us.
It’s fine margins but it comes from mentality & muscle memory - they have players that know how to get over the line. We don’t.
