Claude Puel praised his team for showing a mixture of both quality and backbone in their 1-0 victory at West Bromwich Albion.
Saints ran out deserved winners at the Hawthorns, thanks to Jordy Clasie's first-half goal, although they had to stand up to some significant pressure late on, with Fraser Forster making some vital saves in the dying stages.
"It was a great performance, getting a clean sheet away against West Bromwich, who are a strong side," said Puel.
"We dealt the whole second half with direct play and long balls, free-kicks, second balls. It was very difficult to defend against this.
"It was a very good first half with quality, and we saw the good spirit and character in the second half to resist and to take these three points. Fraser did a fantastic job and he saved the three points at the end of the game.
"It was a whole team effort. When we attack, all the team attacks, and when we defend all the team defends. We saw this. Shane [Long] was coming back to defend, and he produced a courageous game, with fantastic work for the team.
"It's a great result and I am happy. It's fantastic, and I think we deserved this result with our quality in the first half and our character in the second half.
