Manolo Gabbiadini's second-half goal injected life into Southampton's hopes of Premier League survival and leaving Swansea in big trouble.
Swansea City's relegation fears deepened after Manolo Gabbiadini's second-half goal helped Southampton to a nerve-shredding 1-0 win at the Liberty Stadium.
The win moves Mark Hughes' side into 16th place in the Premier League – ahead of Huddersfield Town on goal difference – and they know they will be safe if they avoid defeat against Manchester City on the final day of the season this Sunday.
It is looking increasingly bleak for the 18th-placed Swans, who need to beat Stoke City at the weekend and hope that Huddersfield fail to pick up any points against Chelsea and Arsenal in their remaining two games or that Saints lose heavily to Pep Guardiola's Premier League champions.
