After spending two seasons at Southampton, Ronald Koeman looks set to leave for Everton.
A deal seems inevitable with the Everton owners offering Koeman a significant transfer budget and the ambition to make it into the Champions League.
If Koeman does end up joining the Toffees as expected, it leaves Southampton in a tricky situation, as they look for a manager who can usher in yet another new era.

Quality managers with top level experience are hard to come by and Southampton must be aware of that.
Here are two candidates who could take over and do a reasonable job.
Frank De Boer
De Boer has certainly taken well to managerial duties, winning four Eredivisie titles during his time at Ajax.
The Dutch manager left his post at the end of the 2015/16 season after narrowly losing out on the league title to PSV Eindhoven on the final day.
De Boer is keen for new challenges and the Premier League would certainly provide him with that.
His philosophy was popular among the Ajax faithful, incorporating a possession-based game with individual expression. Southampton fans have been treated to exciting football over the past couple of seasons and De Boer is more than capable of providing that.
The master tactician has been linked with clubs such as Lazio and Everton previously, so Southampton would need to move quickly if they are to have a chance of securing his services.
Martinez would certainly be a controversial and surprising appointment, with Koeman going the other way to Goodison Park.
The Spaniard was sacked by Everton near the end of the season after a disappointing 11th placed finish in the league.
Despite that disappointment, Martinez was tipped for greatness only a couple of seasons back, having guided Everton to fifth place in the league in his first season.
Throughout his managerial career, Martinez has been known for implementing a fluid and exciting brand of football, one that would suit well at a club like Southampton, as he might be able to bring out the best in the likes of Sadio Mane and Dusan Tadic.
After his final months at Everton, Martinez will be desperate to prove the doubters wrong and this fuel could propel Southampton to even greater heights.
Who should Southampton appoint? Is Martinez the man? Have your say in the comments.
