A clinical second-half performance earned Southampton a 3-0 victory and their first top-flight league double over Norwich City.
In their first match back after the COVID-19 outbreak Daniel Farke's side began brightly, with Kenny McLean fizzing a shot wide and Josip Drmic's deflected effort going over.
But Southampton grew into the contest and Danny Ings struck the crossbar late in the first half.
Ings made no mistake four minutes after the interval, curling superbly beyond Tim Krul to put the visitors in front with his 16th PL goal of the season.
Saints doubled their advantage five minutes later, Stuart Armstrong cutting in from the right before dispatching a low left-footed drive into the bottom corner.
Nathan Redmond made it 3-0 with a low strike on 79 minutes as Southampton secured their seventh away win of the season, moving up to 13th with 37 points.
Norwich remain bottom, six points from safety.
