Jason Puncheon says Southampton have finally matured in the Premier League after Saturday's win hoisted them to 15th spot.
Returning to the top-flight after seven years, the Saints began the season with one win in 11 matches, conceding 29 goals on a miserable run.
But after shoring up their leaky defence - four goals in six matches - they collected a second win and a clean sheet in the 1-0 triumph over fellow strugglers Reading.
When asked about how the club had kick-started their revival, the winger said: "I think it was nerves.
"I'll be honest, as a team coming into the Premier League, I think we were a bit nervous, a bit shaky.
"We didn't find our feet or our rhythm and now we have found that and that is showing as a team.
"We haven't got a bad defence. A few of the boys playing in that back four played in the team last season and how many clean sheets were there last season? Now we are gelling and that is showing.
"It is definitely onwards and upwards now. We look forward to the Sunderland game. It is a home game so we need three points again."
