The visitors were looking for a first win at Stamford Bridge in 36 years but were no match for Pochettino’s newly energised side, who after a nervous first half ripped into them late on to earn the manager his first win.
Raheem Sterling continued his fine start to the season with two goals and an assist for summer signing Nicolas Jackson, who opened his goalscoring account for the club.
The England forward’s difficult debut season in west London looked confined to history when he danced through Luton’s defence to open the scoring after 17 minutes, before settling Chelsea nerves with a sweetly taken second midway through the second half.
His assist for Jackson, nonchalantly driving over a low cross after collecting Enzo Fernandez’s clever ball forward, typified a new confidence that has marked early performances under Pochettino.
And the manager stated again that reinforcements, whilst welcome, would only be sought if the right profile of player can be found.
“It’s in the way that we love to work,” he said. “The intensity in the Premier League, if it’s not there, it’s difficult to win games. (We matched) the energy of Luton, and I think that was one of the keys, and after with the quality to score goals and create chances.
“I don’t know about the past, I cannot talk about the past. Only we can talk about the present and the future, and the way we want this pressure and the challenge that is to create a team with full energy but also with quality, to have the capacity to be competitive and challenge the big teams like Liverpool, Manchester City and company.
“I’m very pleased because the performance was very solid but that is only the first step. We need to work really hard to still improve, because I think we are so far in the way that we want to play, we are far away. But I think we are in a very good way.
“Like happened last week when we lost against West Ham, it’s not going to change (our plans). We work and the result (against Luton) was positive.”
