Ghana winger Kamaldeen Sulemana will be working under a new coach at Southampton following the immediate dismissal of Russell Martin after heavy home loss to Tottenham Hotspur in the English Premier League on Sunday evening.
The St. Mary's Stadium outfit announced the sacking of 38-year-old tactician after a 5-0 thrashing by Tottenham this evening left them nine points off Premier League safety.
He guided the Saints to promotion last year in his first season in charge, beating Leeds United in the play-off final at Wembley.
But the loss against Spurs was Southampton's 13th in the league this campaign from 16 games.
Their only win this season was against Everton in November, while the St Mary's club have scored a league-low 11 goals.
"Going into the start of the season, we all knew the challenges that we would face this year as we readjusted to life in the top flight, competing in the best and most competitive league in the world," said a Southampton statement.
"However, the reality of our situation is clear. The board have supported Russell and his staff and been open and transparent regarding our expectations.
"We have all been on the same page in recognising the urgency of needing results to improve.
"We would like to take this opportunity to thank Russell and his staff for all the hard work and dedication they have given the club on and off the pitch over the last 18 months.
"Everyone connected with Southampton FC will always have fantastic memories of last season, especially the play-off final win in May."
Southampton Under-21s manager Simon Rusk will take interim charge of the senior side and his first game will be a Carabao Cup quarter-final at home to Premier League leaders Liverpool on Wednesday.
Martin's dismissal comes on the same day as fellow top-flight strugglers Wolves decided to sack manager Gary O'Neil.
Southampton were 5-0 down to Tottenham before half-time and frustration from some of the home fans was directed at both Martin and club owners Sport Republic.
Sulemana, who was handed his first start of the season by Russell Martin in today's game against Tottenham, was substituted in a shocking manner after lasting only 13 minutes of the game. He was replaced by Nathan Wood.
The Ghana international played an instrumental role in Southampton's promotion back to the Premier League, providing three assists in 25 appearances in the Championship last season.
Sulemana has made only six appearances for the Saints in the Premier League this season so far and expecting to excel under the next Southampton coach.
