The Scottish coach has been in charge at Old Trafford for over 25 years, and feels that the changes he has witness have negatively impacted upon the sport.
“When I first started out in management 37 years ago there were no agents. Imagine that,” the United boss told the FIFA website.
“There was no freedom of contract either, so players were totally tied to their clubs.
“A change in that sense was inevitable, though I think that now the scales tipped completely in the other direction and I’m not sure it’s good for the game.
“Of course the way the media works has changed too, there’s a lot of pressure on journalists to publish huge news stories – not just about sport but about everything – and that’s had an impact on us, no doubt about it.
“In the playing sense, I think the biggest change over the last decade has been the improvement in playing surfaces. They’re fantastic now and, given the technological advances in that area, playing on a poor pitch has become very unusual.
“And the other big change has been in sports science, which has progressed at an astonishing rate.
“For example, when I started out at Manchester United my entire coaching staff consisted of just eight people, and that included my assistant coaches, fitness trainers and scouts. Now I’ve got ten sport scientists! It’s a radical change,” he concluded.
