Southampton made it back-to-back Premier League wins after Pierre-Emile Hojbjerg's fourth league goal of the season secured a 1-0 win over Brighton.
Clear-cut chances were at a premium in a first-half that the Saints shaded, with the best opportunity for a goal coming 11 minutes before the interval, but Danny Ings saw his effort blocked well by Bernardo.
The second period began in much the same vein, with the visitors looking the likelier side to break the deadlock, and they did just that on 53 minutes, as a counter-attack from Southampton was finished well by Pierre-Emile Hojbjerg.
