It's decades of that very glum existence that has created that mentality lol.
I remember in 2012 when the rags went 8 points clear with only 6 games to go. They were all over social media gloating and mocking us, celebrating winning the title. I answered a few of them by saying they better pray they don't blow it now as they'll never live it down. Absolutely zero chance of that was the reply. We all know what happened next
Win their game in hand and the rags are in exactly the same position. 8 points behind with 6 games to go. They are considered to have no chance, not against a highly successful squad motivated by the best manager in world football, exactly as it was for us facing Ferguson's United back then. The way it is panning out is spookily similar, that's why those of us with a nervous disposition and a bit superstitious worry.
