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.
When I first signed schoolboy forms for United, as a midfield player, I felt for a while that I was just treading water.
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.
In my last years, I was conscious how I used to play the game when I first broke through. It was absolute chalk and cheese. I probably finished at the right time. There won't be many players like me in the future.
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 try, when I go into places, not to belittle what's gone before, because I know how difficult it is to manage, and everybody does it differently.
