With Utd supposedly making Southgate their No1 target if Erik ten Hag is sacked, Graham Potter, 48 - who has also been linked to the Reds - could replace him. He's been holding out for the perfect job since being sacked by Chelsea in April, and this could be it.
Eddie Howe is allegedly on the FA's list of potential candidates. However, the 46-year-old apparently does not want to become an international manager at this stage of his career and instead hopes to be at Newcastle for the long run.
Love him or hate him, Jose Mourinho would certainly be an interesting pick. He turned down the job in 2007 but ex-Chelsea star Mario Melchiot says it could be 'the one job in England' the out of work 61-year-old would take.
Pep Guardiola would be a dream pick for most England fans and he has mentioned a desire to one day manage a national team. Should the Spaniard, 53, leave City this season, possibly after another Treble, it could provide a refreshing new challenge.
Sarina Wiegman, 54, is the only candidate to have won a senior international title, having led the Lionesses to Euros glory in 2022. The FA were said to be looking at her as an option, but she has since signed a new deal with the women's team until 2027.
Lee Carsley, 50, has been in charge of England's Under-21s for the last three years, so he has a close relationship with the likes of Levi Colwill, Jarrad Branthwaite and Cole Palmer. He would be following Southgate's path from the U21s to the men's team.
The FA could decide to put a former England captain in charge of the senior squad if Southgate leaves. If so, Steven Gerrard could be the man. He led Rangers to a record-breaking title before a doomed spell at Villa. Now at Saudi side Al-Ettifaq.
