As England search for their sixth manager since the turn of the century, we ask: what makes a successful international coach?
Is it having a wealth of international playing experience with over 100 caps? Is it being the same nationality as the team? Is it having several major honours under your belt?
As the second day of the England inquest gets under way, the discussion begins to move away from Roy Hodgson and towards his successor, whoever that may be.
England's defeat by Iceland in the last 16 of Euro 2016 has them at rock bottom, and though the questioning of mentality, tactics and player pool are valid, the only immediate impact the FA can have is the appointment of a new leader.
Martin Glenn, its chief executive, told the media on Tuesday that they were open to a foreign manager, something England have tested only twice in Sven Goran Eriksson and Fabio Capello.
"We will be looking for the best person for the job. We will not be ruling any person out," Glenn said.
That direction makes sense, given the lack of obvious English candidates, but what does history tell us about foreign international coaches elsewhere?
Only one has won a World Cup or European Championship with a foreign nation - German miracle-worker Otto Rehhagel's success with Greece at Euro 2004 - and when looking back at the managers of the last 15 tournament-winning sides in the last 30 years, the CVs make for interesting reading.
Going back to Argentina's 1986 World Cup success, the 14 different managers have an average age of 56 at the time they won either the World Cup or Euros, but perhaps more importantly, had won an average of 3.9 major trophies.
In the past 15 tournaments, only three major tournament-winning managers had not won a major honour as a coach before their international success; Franz Beckenbauer (West Germany at World Cup 1990), Berti Vogts (Germany at Euro 1996) and Roger Lemerre (France at Euro 2000). The rest had 59 between them.
And what about their experience of playing at international level? As the likes of Arsene Wenger and Jose Mourinho have shown, it doesn't always matter.
Of the 14 managers, only two had over 20 senior caps for their country, with five never playing internationally at all.
And the average number of caps for a tournament-winning manager in the last 30 years? Just 17, a figure which would be lower if not for Beckenbauer and Vogts' 199 caps for West Germany between them.
So, who fits that bill for England? Gareth Southgate is the current favourite due to his experience within the FA and England's youth sides, while Harry Redknapp, Gary Neville and former manager Glenn Hoddle are also in the bookies' reckoning.
You have to dig deep to find the first foreign coaches in the running - the likes of Jurgen Klinsmann, Arsene Wenger, Laurent Blanc and Guus Hiddink.
FA chairman Greg Dyke has expressed his openness to a foreign England boss in the past, saying in 2014: "They wouldn't necessarily have to be English but they certainly would have to understand English football.
"You wouldn't rule out someone who is a Scot or Welsh or French but they would have to understand English football."
FA technical director Dan Ashworth will team up with Glenn and David Gill to choose Hodgson's successor in the coming weeks and months ahead of their first World Cup Qualifying match in Slovenia on September 4.
Ashworth released 'England DNA' back in December 2014, described at the time as "the start point for the creation of a world-class approach of elite player development leading to winning England teams."
The first tournament didn't go to plan, but the technical quality of the England squad has arguably improved. Now, the FA must once again find the man to put the pieces together.
