We are in the entertainment business and we all know if you are top of the tree you get the big money. Those of us who have been in it are the fortunate ones but we understand that we probably don't deserve it as much as the nurses or teachers.
Diving is a really, really difficult one because a player is the only one who genuinely knows whether they have dived. You can look at it at 40 different angles and not know. And you can just fall over, too.
The best, most successful managers in the modern era are those who can keep a player happy even if he is not in the team. Given the size of the squads and the use of rotation nowadays, that's tougher than it's ever been.
It's true: a lot of sportspeople really struggle to find something to do when they finish. It tips them into all sorts of strange things. With ex-footballers, it's really scary. I think 70% of them get divorced within five years. It's hard. You go from being really famous to not that famous. Your salary drops through the floor.
The train's always full of football fans going up to see matches. Oh, they make sure I hear their points of view all right. They all want to have their say about their team, and make their opinions known.
We have got too many kids around the house to have a romantic meal at home. But Danielle is a fantastic cook. She does a brilliant lasagne, great roasts and a great chilli dish. She knows the way to my heart.
I watched Leicester City lose in the 1969 FA Cup final with my dad and granddad when I was eight and cried all the way home. I have seen them get promoted and relegated. I played for them for eight years. I even got a group of like-minded fans and friends to stump up a few quid to salvage the club when they went into liquidation.
That's what being a footballer is, really: you train at this time, you finish at that time, then you do that, then you go home, then you're not allowed out, then you do this... there comes a point in your career - about thirty, thirty-one - when you get a bit sick of being screamed at.
I just think to be a manager you've got to live and breathe and have this incredible enthusiasm for football, the whole thing. And while I love the game, and it's been a large part of my life, it's not the only thing in my life.
Some players are quite homely, and they don't see themselves going abroad; others would relish the challenge. I can only speak personally, but I always wanted the challenge, and to go and live in a place like Barcelona was great.
In terms of the pricing of football tickets, there's no need - given the massive amount of money that's coming in now from television rights, there's no need for them to be greedy. Look after the supporters; make sure they can still afford to go and watch football.
You never know how long a player has left, especially with strikers. Once you turn 30, as a striker, you are usually on the way down, and playing from the age of 16, at such a high level, has to take its toll.
