We all know Queiroz, right?
The Portuguese redefines the word nomadic with every passing year, and at 61 years of age, he is currently in his 12th different role in world football.
He flitted across the globe after ending a substandard playing career in the mid-1970s; Portugal, Portugal U-20s, Sporting, MetroStars, Nagoya Grampus Eight, United Arab Emirates and South Africa all used his services at one time or another.
A strong year assisting Sir Alex Ferguson at Manchester United attracted Real Madrid to his services, and in 2003, he took charge of Los Blancos. A Super Cup win signalled a strong start, but the team fell out of the Liga title race pitifully, surrendering it to Rafa Benitez's Valencia in meek fashion.
He was welcomed back to United and enjoyed a further four years at Old Trafford after receiving the axe at the Bernabeu, and in 2010, he took his native Portugal (again) to the World Cup in South Africa.
His defensive philosophy reared its unwanted head once again, though, and despite hitting North Korea for six, the team failed to score in their other three games.
For Iran, though, that careful nature is welcomed, and the Persian Stars are built upon a solid defensive foundation that will make itself tough to break down at all times. In many ways, it's something of a perfect match.
