The best goalkeeper I played with at United was Schmeichel. He was a phenomenon in training, never mind on match days. He just never wanted to concede, and he would do everything to stop you scoring.
Alisson is undoubtedly one of the best goalkeepers in the world and he deserves to be put on that pedestal. Him and Manuel Neuer are probably the best two when it comes to angles - those two are the very best in the world at getting their angles right, they don't have to dive because they aren't out of position.
You can't win any trophies unless you've got a top goalkeeper.
I regard Buffon as one of the best goalkeepers in the history of football. He is a legend for me, a fantastic man, and an excellent goalkeeper.
Bravo, Marc-Andre ter Stegen, and Jordi Masip are three goalkeepers of the highest quality.
Since myself and a few others like Pepe Reina, we haven't had a goalkeeper who has commanded his area as well as Alisson.
If you are fighting at the top in the Premier League then you cannot do that with a dodgy goalkeeper. It is not possible.
I can't say who is the best, because all of them have their qualities. There are many goalkeepers out there who can make a difference.
As for being the best goalkeeper in the world, it's been written occasionally, but I'd never say it myself.
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.
In the future, you'll see many more nominations for big awards going to goalkeepers.
Courtois was rated highly enough by Chelsea to go back and replace Petr Cech, one of the best goalkeepers of modern times. He has lived up to his reputation.
I've seen my share of bad goalkeeping, and I've had my moments. But I've seen some excellent goalkeeping as well.
Of course, getting to be No. 1 keeper in the world is a tough ask because there are loads of goalkeepers out there and some very good ones, too. But I always try to give my very best to reach that standard.
