Who is Carlos Carvalhal?
That is the question Sheffield Wednesday supporters have been asking since he emerged as first contender and then quickly the shock favourite to become the club’s new head coach after Stuart Gray’s sacking.
And now he is officially the man charged by chairman Dejphon Chansiri to guide the Owls back to the Premier League.
A quick scan of the 49-year-old’s coaching history does not make for the most inspiring reading - 14 clubs led in a 14 year spell, none managed in the last three years.
But the basic facts hide a certain degree of success for the Portuguese.
Carvalhal has led clubs in Portugal, Greece and Turkey with most of his postings coming in his homeland. Results have been mixed but he has led clubs to silverware as well as tasting European football on several occasions.
A former centre-back, mainly with Braga, and a Portuguese Under-21 international, Carvalhal first moved into management in 1998.
He took third-tier Leixoes - his fourth club - to the final of the Portuguese Cup, beating Braga in the semi-finals before losing to champions Sporting in the final, two clubs Carvalhal would go on to manage.
Reaching the final earned a place in UEFA Cup qualifying and he remarkably guided Leixoes into the UEFA Cup first round.
The following season, Carvahal’s Leixoes romped to the Segunda B title, earning promotion to the Portuguese second tier.
He would leave to join Vitoria Setubal, who he guided to promotion into the top flight in his first season, before switching to Belenenses. After finishing his first season comfortably in midtable, he was sacked after a downturn early in his second term.
The following year, in 2006, Carvalhal was handed his biggest job up to that point when he took over at Braga but lasted just 13 games.
Within days of leaving Braga he joined another top-flight side, Beira-Mar but it proved a disastrous and short-lived move.
The club signed an agreement with a Spanish-based sporting company which saw Carvalhal dismissed to make way for Spanish coach Francisco Soler.
In 2007 he returned to Vitoria and managed to rediscover his previous success. Vitoria would finish sixth in the Primeira Liga, earning UEFA Cup qualification, and they also won the League Cup after beating Sporting in the final.
Carvalhal made the surprise switch to Greek outfit Asteras Tripolis in the summer of 2008 but got off to a terrible start and was sacked with the club close to the relegation zone.
The following year he was back in Portugal at Maritimo, helping them to a midtable finish only to struggle the following season and be sacked.
Carvalhal was handed his biggest posting in Portuguese football in 2009 when he replaced Paulo Bento at Sporting on an interim basis from November until the end of the season. Finishing 28 points behind champions Benfica meant he was not considered to stay on.
The following year he moved to Turkey with Besiktas, initially as an assistant. But he quickly found himself in full control when boss Tayfur Havutçu was under investigation for match-fixing.
Carvalhal’s title was interim coach, and his power was often undermined, particularly by a star-packed squad not particularly keen on change.
As Besiktas finished well behind champions Galatasaray, Carvalhal was shown the door as Havutcu returned following clearance of the charges against him.
After Besiktas he stayed in Turkey to run Istanbul Basaksehir but his spell in charge was short in a season which would end in relegation.
For the last two seasons he acted as technical director for Al Ahli in the United Arab Emirates.
Carvalhal also wrote a coaching manual, detailing his style of play and approach while in charge of Besiktas.
