I used to look at the fixtures at the start of a season and mark down what I think we would win or lose depending on home, away who we played the week before etc. I usually gave up after the first couple of months because I'd get it completely wrong. There are just too many variables, shocks and disappointments in sport to rely on it.
I would rather do exactly as the players and enjoy a good win and then concentrate on the next opponents. Doesn't do my dream team any good though
