Southampton have sacked manager Russell Martin after a 5-0 thrashing by Tottenham on Sunday left them nine points off Premier League safety.
Martin, 38, 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.
