It's not pleasant when you lose your whole football team.
If you are at Bayern and lose to Dortmund, it is common that the media voices criticism.
I've been in the position where Liverpool needed to win on the last day to reach the Champions League. In May 2000, we needed to beat Bradford, who were fighting to avoid relegation, at Valley Parade but lost an awful game 1-0.
It goes without saying that when you're the manager of a Premiership club, you go eight miles down the road and get beaten by a team two divisions below you, it's disappointing.
No matter how much money you have or what kind of cocoon you live in, the reality is that you have lost a game of football and let England's fans down. We are bothered.
If, as Bayern, you lose 2-0 at Hertha, nobody believes you that you can still be satisfied with the performance.
My worst moment in football was losing that Champions League final to Barca in Rome.
After Euro 2008, football in England was shattered for a bit, and people were losing interest in following England.
I remember my second game for England - we lost 2-0 to Norway, I was subbed and didn't do myself justice and I thought that was the end of my England career.
I respect his decisions, but football without Messi is not football. It is very hard to imagine football without him.
If Mourinho loses 4-1, he doesn't sleep well.
The Brazilian press doesn't allow us to forget the World Cup in 1950, when we lost the final in a full Maracana.
Football was a natural thing for me, and with no injuries or injury history that would stop me from training, I just enjoyed coming in every day and playing; then it was taken away from me.
That's the unpredictable part, and that's what worries every coach: Protect the football. That's why, when you go into a ballgame, you may be favored, but there's no guarantee you're going to win it.
