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.
I don't think cricket will ever have the same sort of money as football.
Sir John Hall was a multi-millionaire when I came back to Newcastle. With all the players I've bought, I'm trying to make him just an ordinary millionaire.
I admire Arsenal very much, and part of that is that they are profitable.
There's no shortage of investment into Manchester United.
You don't hear a film director saying 'Money mustn't go out of the industry' to actors. You don't hear a concert promoter saying 'We must make sure that money doesn't go out of our industry' to Elton John. Some people in football seem to think, 'Never mind the players, let's get on with the game.'
But what club wouldn't welcome the chance to strengthen their side, what club would turn down the resources Chelsea have?
To compete with the great teams in Europe, you have to invest money. There is no other way to reach that kind of level.
You want all the money inside football. We do not have a bottomless pit of money. There are constraints. That's why some deals I have said no to because of the finances of them.
Manchester City is the richest club in the world. They work to a budget that no one else works to, so they can write their own rules.
I thought always Manchester United can buy every player because they have a lot of power.
Sometimes it looks like the board and the chairman are the worst enemy of the manager and the coaching staff, the football versus the financial side.
We've got to keep the cost of watching football down. If that means players getting the same money for a few years rather than a 25 per cent increase every time, that's fine.
I've seen teams spend £150 million and get nowhere near the Champions League. It has taken Manchester City a billion to get there. There are no guarantees.
When I think about a mid-table club like Everton spending £150 million during the summer, I am lost for words.
Look at Tottenham. You spend over £100-odd million, you'd expect to be challenging for the league.
I used to go salmon fishing with the late Jim Slater, the renowned investor, and he would give me tips. He told me to buy shares in football clubs, so I invested in Manchester United before its shares went through the roof.
There is a risk women's football becomes the most popular spectator sport that fans tune into every four years but are not interested in parting with their money to watch the same players on their doorstep.
Football is becoming all about money. I would like to be in a lift with Gordon Brown and say, 'Please do something about football.'
I have done well out of TV, but not well enough to buy football clubs. I'm not sure it's ever a way to make money.
The Premier League has the power to spend more money on players than the Bundesliga. This is very, very important for players.
I think the way City spends, I would say it's a lot of money. But they spend it in a responsible way. They attract good players, young players and they cost a lot of money.
Once, players came to football expecting to be wealthy when they retired. Now, they expect to be wealthy before they've played their first game!
I kept an interested eye on the transfer window in England, which opened and closed last month, and the lack of frantic activity just goes to show the current financial state of the game right now.
The World Cup must remain the number one competition, because it is our only source of money and, with that money, we can develop football in the whole world.
