Southampton have decided against renewing contract, which expires at the end of the season, of interim coach Ruben Selles.
The club announced the decision on Wednesday after their relegation from the Premier League.
Spanish coach Selles, 39, took charge after Nathan Jones was sacked on February 12 due to poor performance.
Selles led his side to a 1-0 victory over Chelsea in February, which helped him secure the managerial spot until the end of the season.
However, he was not able to help Southampton avoid relegation as they will finish at the bottom of the table and will compete in the second-tier Championship for the first time since 2012 next season.
"Southampton football club can confirm that it has held conversations with men's first-team manager, Ruben Selles, and decided that his contract will not be renewed when it expires at the end of the season," Southampton said in a statement.
"The club wants to place on record its thanks to Ruben for taking on the managerial position at a difficult time for the club and for giving his all as we attempted to stay in the Premier League.
"Ruben will take charge of the team for the final game against Liverpool on Sunday at St Mary's. We wish him all the best for his future career."
Selles joined Southampton in July 2022 as an assistant to Ralph Hasenhuettl. He has previously managed Valencia's under-18 team and has coaching experience in Greece, Denmark and Azerbaijan.
Southampton are like to bring in Swansea City boss Russell Martin as their new head coach, according to reports in British media.
Southampton, who have only mustered 24 points from 37 games, will host Liverpool in their last game of the season on Sunday.
