Every United player understands what United is about. The players understand it is a privilege to play for United.
At United, there has been continuity with the manager, with the success they have had. It gives them a different dynamic.
It's no secret that I enjoyed the physical side when I was a player. I was a bumps-and-bruises man.
I'd knock people over and bruise their pride, but I never went out to hurt people. That is not acceptable, and I don't want to see it in my team.
I suddenly thought, if I was going to make a go of it, I was going to have to look after myself and not keep apologising for knocking people over. That transformed my career.
I had no direct experience of a relegation scrap, but with Wales, I never had the luxury of being allowed to lose games. I was under pressure to win even the friendlies.
If you are loose and not quite taking clear-cut chances in training, then clearly you are not going to do that come match time.
If we are going to ask questions of the defensive guys, then we are going to ask questions of the guys at the top end as well.
There's a full Football League programme every Tuesday, so I see those games and get to check out people like Paul Jones and Robbie Savage by playing against them.
As a player, I had no idea whatsoever about getting a team ready for a game, what it entails.
All the major sports have video reviews, and for some reason, the Premier League, which is watched all around the world, is still in the dark ages.
At City, I didn't realise how much we had to do until we got there. Here, I didn't need to change the staff because there is quality already. So they certainly don't need me getting in the way in training by trying to show I can still play. No way.
Attacking football is what I want to watch as a manager; it's what I want from my teams. It's easier to be destructive and get people behind the ball than to be constructive and creative.
Competing in the Premier League is more difficult than winning trophies in plenty of countries abroad.
If you feel a bit aggrieved or hard done by, you probably need the break just to reset yourself and give yourself time for different learning - to get out there and experience different things.
Sometimes the manager actually is the glue that holds everything together, and when you take that manager out, sometimes that's when things start to go really wrong.
The four and a half years I had at Stoke is something I will always look back on with pride because it was a huge achievement. To be able to last in a high profile job as long as I did showed that, for the most part, I did a decent job there.
I would like to think that during my time at Stoke - and other clubs I was at - I was always a manager that wanted to play in the right way, with purpose, with drive, and to try to dictate to the opposition if you could.
You can't manage one size fits all; you've just got to know your group and know what ticks players' boxes.
There are certain games where you have to hold your hands up, take your medicine, and move on to the next one.
