Southampton unveiled Mauricio Pellegrino as their third manager in as many seasons on Friday.
Pellegrino, 45, won the race to replace the sacked Claude Puel ahead of Dutch legend Frank de Boer as Saints chiefs were impressed with how the Argentine guided little Alaves to the Spanish cup final and see similarities with fellow countryman and their former boss Mauricio Pochettino.
But what five things does Pellegrino need to do to ensure he matches Pochettino’s success on the south coast?
Van Dijk’s on-off move to Liverpool has been one of the sagas of the summer so far.
Although the Merseysiders withdrew their interest after Southampton accused them of tapping the player up, there are still plenty of other suitors for their captain. Chelsea are reportedly lining up a £60 million bid to test Southampton’s resolve, so it is up to Pellegrino to convince the Dutchman he can satisfy his ambitions on the south coast.
The same goes for England left-back Ryan Bertrand, who is reportedly keen on linking up with Pep Guardiola at Manchester City.
Puel did not so much lose the dressing room as he never really won it over in the first place. His lack of charisma had several senior players doubting him from the start and that lack of rapport with his players was one of the key factors why he was fired despite leading Southampton to an 8th place Premier League finish and to the EFL Cup final.
One of Pellegrino’s biggest challenges will be to breathe fresh enthusiasm into a squad who by the end of Puel’s short-lived reign were left feeling flat and disenchanted.
That is why the new manager’s work on the training ground in the early weeks of his tenure and during preseason will be doubly important.
Sign at least one top class centre-back
As a former defender himself, the ex-Liverpool star will be well aware of the importance of building a successful team from the back.
Southampton never replaced former captain Jose Fonte following his January move to West Ham and even if they convince Van Dijk to give them one more year, finding a top level partner for him is a must.
Rookie Jack Stephens and the previously maligned Maya Yoshida did an outstanding job as fill-ins at the end of the season but should be no more than squad players in a team with genuine European ambitions.
The lack of goals – especially at home where they scored 17, the same as relegated Middlesbrough – was the single biggest blight of Puel’s stewardship. The fact Charlie Austin finished the season as their second top-scorer (six, one behind Nathan Redmond’s seven) despite being out injured from December until the final weeks of the season tells its own sorry story.
Pellegrino has plenty of forward options at his disposal, with Austin, Manolo Gabbiadini, Shane Long, Dusan Tadic and Redmond in his ranks but needs to find the right combination to get the goals flowing again.
Southampton supporters struggled to relate to Puel and never once sung his name. They found his football a turn-off and his news conferences dull.
Pellegrino is regarded as a more dynamic character and a strong relationship must be built between the fans and the man in the dugout to help the players on the pitch.

So the managerial merry go round has ended up spitting Mauricio Pellegrino out at St Mary’s.
The Argentinean - a former boss at Valencia, Estudiantes, Independiente and Alaves - joins the Saints on a three-year contract to replace the sacked Claude Puel, with the remit surely to play some more attacking football following the largely dour stuff that the Frenchman’s teams often produced last season.
The experience at those aforementioned clubs in Spain and Argentina will surely serve him well, but Pellegrino can also call upon some knowledge of English football following his time both playing and coaching at Liverpool.
A former defender, Pellegrino was brought to Liverpool by Rafael Benitez on a six-month deal in January 2005, and he served as valuable cover for both Sami Hyypia and Jamie Carragher in the latter half of that season, with the Reds going on to win the Champions League.
He then returned to Anfield as Benitez’s first team coach in 2008, before departing in 2010.
And Reds fans think that his new position at Southampton - a club they’ve come to enjoy shopping at in recent years - can only mean one thing…
So will “Agent Pellegrino” do his thing and let Virgil van Dijk move to Liverpool?
Southampton legend Francis Benali has told talkSPORT 2 of his optimism over the season ahead following the appointment of Mauricio Pellegrino.
The Saints confirmed Pellegrino as first team manager on Friday, just over a week after the sacking of Claude Puel.
While Puel guided Southampton to an eighth-place finish last term – not a bad position on paper – there was frustration across the club that their identity on the pitch had been lost under the Frenchman.
His replacement, Pellegrino, who was assistant manager to Rafael Benitez at Liverpool between 2008 and 2010, is relatively unknown by both the St Mary’s and rival support.
But as discussed with Benali, former Saints boss Mauricio Pochettino was similarly someone many asked ‘who’? when he arrived on the south coast four years ago.
“You look back at the recent appointments, in recent years, and going back to [Mauricio] Pochettino, [Ronald] Koeman, and even Claude Puel, they’ve all come in and done an outstanding job,” Benali told talkSPORT 2.
"That’s why I’m comfortable with the appointment the club have made; you know they certainly wouldn’t have made the decision lightly to let Claude [Puel] go, and likewise they’ve certainly got a selection process, an appointment process of new players and managers that stands out from other teams.
“I’m keeping my fingers crossed that things will go well for him, but it’s going to be tough, because the Premier League can be a pretty formidable place to come and play and manage.”
Benali also spoke of the opportunity players at Southampton, particularly those who may have struggled under Puel, now have to suggest they deserve a place in the team.
"It’s going to be an opportunity for every single player at the club… a clean slate for players that were playing regularly under Claude Puel – they’ve got to almost go out and prove themselves again.
“It’s an opportunity for players that may have not figured much to impress the new manager, but he’ll have to come in and have a few conversations with one or two key players that have been linked with moves away from Southampton, and put his spin on why Southampton are the club to play for and he the manager to play under.”
