Swansea sacked head coach Paul Clement on Wednesday night with former Newcastle midfielder Michael O'Neill in the running to replace him.
The 45-year-old paid the price for a run of poor results that left the Swans rooted to the bottom of the Premier League, four points from safety.
Take a look at the contenders ...
O'Neill's stock is high after leading Northern Ireland to Euro 2016 and narrowly missing out on guiding them to the World Cup in Russia next summer. The 48-year-old has had plenty of admirers for his heroics in international management and could now be tempted to join a Premier League club. He would be faced with a similar situation to the one he found when he took over at Northern Ireland, needing to sort out the team from the back.
The Newport-born 59-year-old is currently out of work following his sacking by West Brom last month. The Baggies and Crystal Palace have both turned to Pulis over the last few seasons to guide them away from danger. But would Pulis put his record of never taking a club down from the Premier League at risk at Swansea? He would appear to be the best candidate to attempt to get Swansea out of trouble, though.
Like Pulis, Koeman is a manager with Premier League experience currently unemployed. The Dutchman, who spent over £100million in the summer, was sacked by Everton in October following a dismal run of form. At Swansea Koeman, who has recently been linked with the Holland job, would pick up a team in a similar state to the one he left at Goodison Park.
The 35-year-old midfielder was named as Clement's assistant coach in November following the departure of Claude Makelele and he knows the club inside out. Having initially joined in 2003, Britton briefly left the Liberty Stadium in 2010 to join Sheffield United but returned less than a year later and has remained in Wales ever since. The Swans have hired from within before when they appointed Garry Monk in 2014.
