The Saints tried their luck with three different managers and sacked two of them in an attempt to climb away from danger, but their youthful squad built with 15 new signings across two transfer windows ultimately lacked the experience and quality to move away from the dreaded dotted line.
Here, Sports Mole takes an in-depth look back at Southampton's dismal 2022-23 season which saw them relegated from the top flight after finishing rock bottom of the table.
SEASON OVERVIEW
Final league position: 20th
EFL Cup: Semi-finals
FA Cup: Fifth round
Top scorer: James Ward-Prowse (11)
Most assists: James Ward-Prowse (5)
Southampton had reason to be optimistic heading into the new campaign six months after Chinese businessman Gao Jisheng decided to sell his 80% stake to Sport Republic, headed by Serbian investor and chairman Dragan Solak.
The Saints' summer transfer business was heavily influenced by head of senior recruitment Joe Shields, who left a similar youth role at Manchester City in June to take up his position at St Mary's. Highly-rated teenager Romeo Lavia arrived two days before Shields from the Etihad Stadium, while Gavin Bazunu, Sam Edozie and Juan Larios also joined from the Citizens on permanent deals.
Southampton made 10 summer signings in total, spending around £60m, and the ethos of growing potential at the club was clear as their recruitment included four teenagers, two 20-year-olds and four players aged 25. Meanwhile, the likes of Oriol Romeu, 30, Fraser Forster, 34, and Shane Long, 35, all left the club permanently, and there were also a number of loan departures including Nathan Tella to Burnley and Jan Bednarek to Aston Villa, although the latter returned in January.
Ralph Hasenhuttl was tasked with integrating the large number of exciting young players into his system as quickly as possible, and the Saints made a respectable start to the campaign, accumulating seven points from their opening five Premier League games in August - including 2-1 wins away at Leicester City and at home to Chelsea - and they also progressed past Cambridge United in the EFL Cup second round.
However, Southampton's form declined rapidly and they plummeted into the relegation zone courtesy of a nine-game winless run. Injuries and mass rotation did not help their cause, but with little signs of progression under Hasenhuttl, the Austrian was relieved of his duties after four years in charge of the Saints following a 4-1 home loss to Newcastle United in their penultimate league match before the World Cup break in early November.
Ruben Selles was placed in temporary charge as Southampton scraped past League One outfit Sheffield Wednesday on penalties in the EFL Cup third round, before the Saints moved quickly to appoint Nathan Jones as their new head coach on a three-year deal, with the Welshman opting to leave the successful project he had built at high-flying Luton Town in the Championship.
There were high hopes that Jones, the 2021-22 Championship Manager of the Season, could replicate his success with Luton in charge of Southampton in the Premier League, but it soon became evident that the 49-year-old was incapable of sparking a much-needed revival on the South Coast.
Although the Saints had a successful spell in the domestic cups - advancing to the FA Cup fourth round and EFL Cup semi-finals, with a surprising yet deserved quarter-final triumph over Man City in the latter competition followed by a 3-1 aggregate loss to Newcastle in the last four - their harrowing form in the Premier League ultimately led to Jones' swift departure from St Mary's.
Jones had overseen a January spending spree close to £60m, with Carlos Alcaraz proving to be the pick of the purchases, while Kamaldeen Sulemana - a club-record signing - Paul Onuachu, Mislav Orsic and James Bree all failed to make the desired impact, particularly the latter three who started only eight league games between them.
Despite bizarrely labelling himself as one of the best managers in Europe with Luton last season, Jones lost eight of his nine Premier League games as Southampton boss - including seven defeats by teams outside the so-called Big Six - and the toxic atmosphere generated from the St Mary's faithful following a disappointing 2-1 defeat to 10-man Wolves in February gave the club's hierarchy no choice but to sack the man they hired just three months earlier.
While Southampton searched for a successor to Jones, who left the Saints rooted to the foot of the Premier League table and four points adrift of safety, Selles stepped in on an interim basis for a second time, although at this point he was keen to take the top job full time.
Those hopes of becoming the club's new head coach were significantly boosted after he successfully led Southampton to a surprise 1-0 win away at Chelsea, courtesy of a stunning James Ward-Prowse free kick. Selles was eventually rewarded with the permanent job until the end of the season after talks with former Leeds United boss Jesse Marsch broke down.
The Spaniard failed to build on his impressive triumph at Stamford Bridge, though, as Southampton suffered back-to-back defeats against Leeds and Grimsby Town, losing in frustrating fashion to the latter in the FA Cup fifth round. However, the Saints responded with a rare home victory over Leicester, just their second and final home win of the campaign, to climb off the foot of the table.
Southampton then earned a respectable point in a goalless draw at Man United in the middle of March, but that result proved to be the beginning of a winless 13-game run that stretched until the final day of the season. Selles was ultimately unable to get the best out of his youthful crop who picked up just four points from the last 39 available.
A chaotic 3-3 draw with title-chasing Arsenal in April seemed to knock the stuffing out of the Saints after they let a two-goal lead slip with just two minutes of normal time remaining, before a 2-0 defeat at home to Fulham the following month confirmed their relegation to the Championship with two games to spare.
After Southampton confirmed that Selles would not have his contract renewed in the summer, the Saints managed to avoid finishing the season on a whimper as they played out a frantic 4-4 draw at home to Liverpool, with Diogo Jota preventing the hosts from claiming a final-day victory by netting a 73rd-minute equaliser.

HOW DID IT COMPARE TO LAST SEASON?
After back-to-back 15th-place finishes under Hasenhuttl in the previous two Premier League campaigns, Southampton ended the 2022-23 season rock bottom of the table for the first time since 2004-05.
The Saints managed to reach the 40-point mark last year with nine wins, 13 draws and 16 defeats from 38 top-flight matches, but they could only notch up a measly 25 points this term after winning the fewest games in the division (six) and suffering a club-record 25 defeats.
Southampton actually picked up more away league victories (four) this season compared with last year (three), although their form on home soil suffered a sharp decline as they won just twice and accumulated only 11 points from 19 matches at St Mary's, 14 points fewer than in 2021-22.
The South Coast club also finished this season with the worst goal difference in the division (-37) after scoring just 36 goals compared with 43 netted last year while conceding the second-most goals in the top-flight (73) behind Leeds (78), having let in 67 last term.
After failing to progress beyond the fourth round of the EFL Cup in the previous four seasons, including a fourth-round exit last year, Southampton managed to secure an impressive win over Man City en route to the semi-finals this time around, before missing out on a trip to Wembley after losing over two legs to Newcastle in the last four.
However, they failed to progress as far in the FA Cup as they suffered a shock fifth-round exit to League Two outfit Grimsby, a year on from reaching the quarter-finals and two years after progressing to the semi-finals.
PLAYER OF THE SEASON: JAMES WARD-PROWSE
At the age of just 19, Romeo Lavia deserves a special mention after excelling in a poor Saints side in his first season of senior football following his summer move from Man City.
However, it is difficult to look beyond the contribution of club captain and chief creator James-Ward Prowse, who was once again their main source of goals as he admirably led by example in centre-midfield.
After finishing last season with the most goals and assists for the Saints, Ward-Prowse came out on top in both categories once again this term as he registered 11 goals and five assists in 45 games across all competitions, including three trademark free kicks.
A product of Southampton's academy, Ward-Prowse is the club's all-time record appearance-maker in the Premier League (343) and he played a total of 3,973 minutes in all tournaments this campaign, at least 600 minutes more than any of his teammates.
The 28-year-old showcased his playmaker qualities with more progressive passes (189) and more crosses completed (274) than any other Saints player, while he also deserves credit for putting in the hard graft after winning more tackles (40) and more interceptions (59) for the South Coast club.
Attempting to keep hold of Ward-Prowse is now the challenge for Southampton, but relegation could prove to be the catalyst for a summer departure after two decades at St Mary's.
STANDOUT RESULT: SOUTHAMPTON 2-0 MANCHESTER CITY
Arguably the only success story of Southampton's season was their journey to the EFL Cup semi-finals and they had to pull off a giant-killing against none other than perennial winners Man City to progress to that stage.
