Iain Dowie famously coined the phrase 'bouncebackability' to describe Crystal Palace's ability to come from behind. But this is a typical manager's idea, so optimistic. What fans are interested in is 'throwawayability': which teams toss away hard-earned leads? Now we know that 'throwawayability' exists because we proved last season that 'bouncebackability' exists (although, hilariously, Palace don't have it) and 'throw-awayability' is the flip side of it.

You know what I wonder about? This - the more details of Sven-Göran Eriksson's love life that appear in the press, the more contempt he attracts for his choice of substitutes in England games.

You may wonder why a question of manners has got me so exercised. It's because I believe in a simple rule. If you see a person you know behave unreasonably to someone else, you can bet your last pound that before long he'll be behaving like that to you.

It will be my birthday on Tuesday. Last year, I reached the painful conclusion that there wasn't enough time left to read every book ever written. This year, my gloomy realisation is even more painful - I will not be able to correct everyone's mistakes before I depart.
