The Argentinian oversaw his fourth win at the Saints helm on Saturday and third in succession as he overcame the man he succeeded in January, Nigel Adkins.
Now Reading boss, Adkins was unable to exact any revenge for his sacking as Jay Rodriguez and Adam Lallana goals either side of half-time secured Southampton a 2-0 win at the Madejski Stadium.
Pochettino and Adkins shared a bottle of wine after the match, before which the former was keen not to discuss what was different under his reign.
"It is not really important," he said. "What is important is that we won, have 37 points. I don't really analyse that.
"I think I am a pretty relaxed person, I look to work with my players on the training pitch.
"I think the team has been playing well and I just stand on the sidelines. I am proud of what the players are doing.
"The club have brought me in to do a job and I am doing it well so I am just pleased overall."
Such is the job that Pochettino is doing that Saints ended Saturday in 11th place and seven points clear of the drop zone.
Asked if top-flight football is all but secured for next season, he said: "I have been managing the team for 10 games now and I have never spoken about any goals for the end of the season.
"Only the next goal, the next objective and that is the next game."
That match pits Southampton against West Ham, where they can pick up a fourth successive win.
It also gives Rodriguez a chance to continue is fine recent run, which has seen him net in the defeats of Liverpool, Chelsea and Reading.
"He has scored in the last three games but it is not just the goals," Pochettino said.
"He provides a lot of other things that we ask him to do especially well so we're really pleased with him."
Things are not so rosy for the man that paid £6million to bring Rodriguez to St Mary's, with Adkins now all but certain of facing the drop with Reading.
Seven points adrift with just six games left, relegation seems all but certain for the Royals - not that top scorer Adam Le Fondre will be giving up.
"We've got to start expressing ourselves on the ball a bit more," he said.
"And we'll pick ourselves up and go again. It's not in our make-up to give in.
"Never say never and until it's mathematically impossible, we still believe.
"We'll always battle to the end - that's what the fans expect from us and it's what we expect from ourselves.
"We're paid professionals and we'll give our all for the cause.
"We've got Liverpool here next weekend and we love games like that, so we'll welcome the challenge and try to make it horrible for them."
