United fan James Lawton in the Independent:
'Another milestone for Sir Alex Ferguson, his 21st anniversary today at Manchester United as the most consistently successful manager in the history of English football.
'Twenty-one years at one football place, 21 years when ambition is rekindled as formally as we turn back and forward the clocks, is a phenomenal circumstance, and permits no routine explanation. It is true that his great predecessor Sir Matt Busby went 23 unbroken years at Old Trafford, built three great teams and survived, bruised and agonised in the spirit, the tragedy of Munich. But then if Sir Matt climbed great pinnacles, he also had years of pause, gaps in success that would have tormented Ferguson to the point of distraction.
'Because of his nature, Busby was easier on himself - and the rest of the world. Ferguson has never stopped running, in ecstasy at moments of supreme triumph, and in anger when things haven't worked so well. He is fuelled by joy and rage and adrenalin. In another man it might be a toxic mix. For Fergie is it is life-sustaining.
'For some the celebration of Ferguson's 21 years at Old Trafford needs to be muted. Yes, he has proved himself a natural-born winner, but what about his bullying style, his refusal to see any point of view but his own? Someone said he could have caused a row among the flower people of Woodstock, possibly even at the Last Supper. No doubt they are right, but then Ferguson is what he is and the results have been tumultuous. If we salute Wenger for the artistry of his football - and recognition is, understandably enough, running at a flood time now - is he any better able to step away from the trenches than his fiercest rival? Does it not hurt him just as badly to lose, and are the results often not equally unedifying? Of course, the answers are yes.
'Today we have to judge Ferguson on his work and who can say that, when you bring it all together, it does not represent a hugely rich contribution to the English game? He has given us great players, underpinned by ceaseless ambition, and if there has been ruthlessness, if such separate characters as Roy Keane and David Beckham have been let go without, in the end, a sliver of sentimentality, it has been the mark of his understanding of how to develop a team. Like Busby, he has made three championship teams. Unlike Busby, he has been careless in the matter of creating waves of controversy - and shaping his image. His signings have not been unerringly brilliant and sometimes his tactics have been open to question.
'But now we are in the margins of astonishing achievement. Above all, he has demanded competitive honesty from his players, and never was the result more spectacular than at the Nou Camp in 1999, when a team who looked beaten found something that carried them beyond the normal boundaries of commitment. He could have gone then, with the historic hat-trick of league title, FA Cup and European Cup gathered in at the age of 57, and of course some urged him to do so. The advice has punctuated recent years, but, except for one period of indecision, it has been brusquely rejected.
'In this we find the great and continuing redemption of Alex Ferguson. He cares less for his reputation as a gentleman of sport than the sting of battle. He ignites the game to which he has devoted his life and because he cares so much, and whatever we think of his style, so do we. It means that today the toast is not so much to a unique football manager as the sheer force of life.'
