Following Mark Hughes' sacking at Southampton, we look at the contenders to secure the vacant position at the Premier League club.
An instant early mover in the market, backed into favourite having been a 22/1 outsider.
Hasenhüttl has spent his entire managerial career to date in Germany, managing Unterhaching, Aalen, Ingolstadt and most recently RB Leipzig.
He left Leipzig in May of this year having failed to agree on a new contract, that's despite overseeing a remarkable rise to the top-end of German football.
A 48% win ratio in two years at the club highlights the impact he made. They went 13 games unbeaten at the beginning of the 2016/17 campaign, the longest unbeaten run by a newly-promoted Bundesliga side.
He also led the club to the Champions League, less than a year after they had been promoted to the German top-flight.
A familiar name in English football following stints at QPR, Swansea and Leicester, Sousa is in the market for a return following time spent in Europe.
The 48-year-old recently spent two years at Serie A side Fiorentina, posting a 45.3% win ratio, although did follow that up with an average spell at Chinese Super League outfit Tianjin Quanjian.
Since departing Leicester after just three months and one win in 2010, Sousa has gone onto win Hungary's Ligakupa with Videoton in 2011, the Israeli Premier League with Maccabi Tel Aviv in 2014 and the Swiss Super League at Basel in 2015.
Sousa enjoyed a playing career at European giants such as Juventus, Borussia Dortmund and Inter. Now, you imagine he'll be eager to make an impression in the Premier League.
Quique Sanchez Flores
The former Watford boss finds himself as the early favourite to take the reigns at St. Mary's.
Sanchez Flores enjoyed a fairly successful time during his one season at the Hornets, finishing in a comfortable mid-table position and reaching the semi-final of the FA Cup.
He also earned the Manager of the Month accolade in December 2015 with a record of four wins and just one defeat.
Flores is no stranger to success having won the Europa League and UEFA Super Cup with Atletico Madrid in 2010, while also lifting the Taca da Liga at Benfica in 2009.
He has most recently been in charge at Spanish side Espanyol and was on the shortlist for the Egypt job in the summer, although he eventually lost out to Javier Aguirre.
A name well known among English football fans, Sam Allardyce implements an effective style of football which may be what is required at Southampton to stay up.
The 63-year-old guided Everton to a top-half finish last season despite flirting with relegation during the early part of the campaign, before the Toffees elected to hand Marco Silva the job in the summer.
Allardyce has success on his CV after guiding Bolton and West Ham to the Premier League. He would also go onto manage Sunderland and Crystal Palace in the Premier League alongside a short stint as England boss.
He is someone who has been heavily praised by former players for his preparation for matches and his use of sport science to try and get the best out of players - but Jose Mourinho did label his football 'from the 19th century' when his Chelsea side faced the Hammers in January 2014.
Another name with plenty of Premier League experience, and someone who is currently out of work.
Moyes spent 11 years at Everton, but is more likely referred to by his brief spell in charge of Manchester United.
He lasted less than a season in the Old Trafford hot seat, with the Community Shield the only accolade to show for his efforts.
Moyes then moved onto Real Sociedad in La Liga but would be dismissed after 12 months, then posting his first relegation with just eight wins in 43 seeing Sunderland drop out of the top-flight.
West Ham would be his most recent club. He posted a 29% win ratio during a short six-month stint at the London Stadium.
The Hammers would be the club where Moyes made history though. Their 4-1 victory away at Huddersfield was his 200th win in the Premier League, joining Sir Alex Ferguson, Arsene Wenger and Harry Redknapp as the only managers to do so.
