Pochettino took over from Nigel Adkins in January and looks to have cemented Southampton's place in the Premier League for next season.
But the 41-year-old believes Saints could be in a better position and admits they should have picked up more points.
Pochettino said: "I'm pleased and satisfied with how the team has been playing, but you always need a bit of dissatisfaction.
"All the games that I manage - whether they are at home or away - are winnable, so I want to win."
Meanwhile, Pochettino is relishing the prospect of facing Michael Laudrup again when Southampton travel to Swansea on Saturday.
The ex-Espanyol boss faced Laudrup when the Swansea manager was coaching in Spain.
"I'd like to congratulate Michael Laudrup because he's having an amazing season," said Pochettino.
"Swansea's brand of football is established, and quite similar to what we're trying to achieve at Southampton."
"The style of football he plays at Swansea suits him, and it is similar to the style he was playing in Spain."
