At 58, Bradley arrived in English football having put in the hours during three-and-a-half decades in the dugout.
He has worked in American club football, as well as in Norway and most recently France.
At international level, he had five years as the United States’ national boss and also had a stint in charge of Egypt.
He is regarded as a ground-breaker in the American game - a man who is leading the way for coaches from the other side of the Atlantic.
As well as vast experience, he brings strength of character to the Liberty Stadium, and is viewed as someone who will have an immediate impact in the Swans dressing room.
He has impressed the club’s hierarchy — Jason Levien, Stephen Kaplan and Huw Jenkins — with his leadership qualities as well as his thoughts on how football should be played.
Bradley’s aim will be to produce a Swans team playing the sort of high-tempo, high-intensity possession game which has brought the club so much success in their recent history.
He is known as a manager who likes a challenge, and his task in SA1 will be to inspire a Swans side who have won only one of their first seven Premier League games this season.
Bradley will be confident that he can do exactly that.
He was in his early 20s when he took his first steps in coaching with various American college teams.
His achievements at that level saw him join DC United as assistant boss to Bruce Arena — another celebrated American coach — in 1996.
Two years later, he landed the manager’s role at another MLS club, Chicago Fire.
During four years in Chicago, he won the MLS Cup and two US Open Cups, and lifted the MLS coach of the year award in 1998.
Bradley also had spells in charge of two more American top-flight clubs, the Metrostars and Chivas USA, before securing the job of national manager in 2006.
Bradley led the USA to Concacaf Cup glory in 2007, then to the runners-up spot in the 2009 Confederations Cup.
His team stunned the all-conquering Spain side of the time— they were unbeaten in 35 games before losing to the Americans — en route to the final, where they led Brazil 2-0 only to end up losing 3-2.
Next Bradley took his team to the 2010 World Cup, where they famously drew with England.
Another draw with Slovenia plus a win over Algeria saw Bradley’s men top their group, but they were eventually knocked out by Ghana in the last 16.
Bradley left the American job in 2011, and later that year took on the task of managing Egypt.
Bradley won praise for living in Egypt at a time of political unrest in the country, and won credit for going close to delivering qualification for the 2014 World Cup.
When the Pharaohs did not make it to Brazil, Bradley moved on, becoming the first American manager to take charge of a top-flight European club when he was appointed boss of Norwegian club Stabaek in 2014.
He impressed in Norway, taking an unfancied side into the Europa League, before joining French second-tier club Le Havre in November 2015.
Once more Bradley was praised for his work, as Le Havre only missed out on promotion to Ligue 1 on goals scored.
Now comes the chance to win more plaudits in the Premier League
