Southampton climbed out of the relegation zone and eased some of the pressure on manager Ralph Hasenhuttl by beating rivals Bournemouth 1-0 at the Vitality Stadium.
Che Adams' fine early header (9) was the difference as the visitors ended a five-match winless run in the Premier League.
Despite dominating the second half, Bournemouth struggled to create any clear-cut chances until Mohammed Salisu's goal-line clearance in stoppage time ensured Southampton held on for their first win since the end of August.
The result also saw the Saints record their first clean sheet in the league since a 1-0 win over Arsenal in April. They move up to 14th in the table.
As for Bournemouth, their unbeaten start under interim head coach Gary O'Neil is over after seven games. They remain 11th.
