If you look at my professional history as a goalkeeper, I'm not somebody who makes many.
Buffon may be a bit smaller, but he has everything that you want from a great goalkeeper. He relays his confidence to his defence, and they feel that they have a great keeper behind them. Everybody can make mistakes, but his consistency level is amazing. You never see him have a bad game.
Everybody makes mistakes, but when goalkeepers make them, it is costly. That's the nature of being a goalkeeper.
As a goalkeeper, if you make 10 world-class saves but then miss one shot, or you let in a pass, you're there in the highlights afterwards - and, let's be honest: that is what most people see.
Freak mistakes happen sometimes as a goalkeeper that if you make them, then it's always going to bite you.
A goalkeeper's mistakes are always crucial ones - or get talked about a lot.
I have always said that a striker scores a goal but not every goal is scored by a striker. A goalkeeper can make a mistake which is a goal, but every goal still goes past him and you have to accept that.
As a goalkeeper, I'm well aware that any mistake can be magnified by the fans. But it's true that here at Manchester United, there's added pressure.
If you concede a goal, it can be up to seven or eight mistakes leading up to it but, obviously, as a goalkeeper you have to accept it has gone past you.
Every player makes mistakes; every goalkeeper makes mistakes. Every manager does, every broadcaster - every person in life makes mistakes. But for goalkeepers, often when they make a mistake, it leads to a goal.
I've seen my share of bad goalkeeping, and I've had my moments. But I've seen some excellent goalkeeping as well.
Yes, obviously goalkeepers do the same training sessions and know about things - they are the only ones who can speak about being a goalkeeper because they have done the job and experienced it and know what it is like to make an error and be criticised.
