There is definitely that. I do it when a close rival is playing. I say about the opposition, "They'll never score even if they played all year." Or, "No way can they hang onto that lead for the rest of the game." It worked commenting on dippers games when they were right in the title race. Well I liked to think it worked lol.
As for Sunday on paper we win the game nine times out of ten. The same as if we played that game against Real Madrid we lost on penalties, we win that game nine out of ten times. We all know that football can be like this, hence the nerves.
The universe has a way of evening things up sometimes too, which is why I hate some of our fans over confidence or arrogance at times. Tempting fate they call it. A nagging bit of me feels because we've won games last gasp that we were dead and buried in we might lose one, the universe evening things up. I pray I'm wrong of course and we're 3-0 up in the first 10 minutes and Arsenal are losing to Everton. Please God/universe!
