The following five managers are the most accomplished head coaches the world have ever known, all of them with differing methods, but united by the desire to succeed at all costs.
These managers have won a plethora of trophies between them, although this is not the only method of measuring their greatness as the teams they have built has also been used to create this list.
5. Helenio Herrera (Puteaux, Stade Francais, Real Valladolid, Athletico Madrid, Sevilla, Belenenses, Barcelona, Inter Milan, Roma and Rimini)
Widely regarded as one of the most innovative managers in history, Herrera transcended the way the game is played today.
During his time at Internazionale, he enhanced the 5-3-2 formation to make it more receptive to counter-attacking possibilities (known as the Catenaccio).
Upon his move to Roma, Herrera became the highest-paid manager in the world. In total, he won 17 trophies for his clubs including four La Liga titles, three Spanish Cups, three Serie A titles and two European Cups.
4. Sir Matt Busby (Manchester United, Great Britain and Scotland)
Until Alex Ferguson came along, Busby was considered to be the greatest manager in Manchester United's history, developing the famous 'Busby Babes'.
He is also part of a tragic story, bound by the Munich air disaster which saw the Manchester club lose some of its brightest stars.
His honours grant some testament to his prowess as a manager, with five English League titles, two FA Cups, five Charity Shields and a European Cup.
3. Sir Bob Paisley (Liverpool)
Under Paisley's guidance the Anfield club became one of the most feared and powerful clubs in world football.
He engineered a period of dominance that saw Liverpool win six English League titles, three League Cups, six Charity Shields, one UEFA Cup and an unprecedented three European Cups.
Bill Shankly may have developed the foundations of Liverpool FC but Paisley turned them into one of the most magical teams ever.
2. Rinus Michels (Ajax, Barcelona, Netherlands, Los Angeles Aztecs and Bayer Leverkusen)
Although players such as Johan Cruyff get a lot of the credit for the footballing philosophy of 'Total Football', it was concocted by Michels.
This revolutionised the way that football is played due to the fluid nature upon which it is based, stating that any player can fill the role of another when required.
To highlight the impact that Michels had on the clubs that he managed one only needs to take a look at his bulging trophy cabinet.
With four Dutch League titles, a Dutch Cup, a Spanish League title, a Spanish Cup, a European Cup and the 1988 European Championship with Holland to his name, it is no wonder that Michels was selected as Manager of the Century by FIFA in 1990.
1. Sir Alex Ferguson (St. Mirren, Aberdeen, Scotland and Manchester United)
There is little that remains to be said about the Old Trafford stalwart but I shall give it a go regardless.
Ferguson is just the most sensational manager of all time. That is not just because of his trophies, it is the way in which he won them.
Some of his teams he developed into legends, while others he made them victorious through sheer willpower and an air of invincibility.
Even United squads that lacked quality always somehow found the desire to win and, more often than not, emerged victorious.
In his illustrious managerial career Ferguson has attained practically every trophy available to him with a jaw-dropping four Scottish League titles, five Scottish Cups, 13 Premier League titles, five FA Cups, four League Cups, 10 Community Shields and two Champions League victories.
In 27 years at Manchester United, he only lost 267 games out of 1500, with 895 wins: a truly phenomenal manager and certainly the greatest in history.
Although it is fair to say that this does represent the very best of managerial talent over the years, there are some coaches who just missed out and, therefore deserve honourable mentions.
Managers such as Arsene Wenger, Ernst Happel, Bill Shankly, Vittorio Pozzo, Brian Clough, Jock Stein, Jose Mourinho, Pep Guardiola, Sir Bobby Robson, Sir Alf Ramsey, Ottmar Hitzfeld, Giovanni Trappattoni among others, all are worthy of special acclaim, although they are just not a par with those in the top five.
Of course, all of this is massively opinion-based and there will be many who disagree with this list entirely.
