The Argentinian replaced Nigel Adkins at St Mary's last season and guided Saints to a 14th-placed finish on their return to the Barclays Premier League.
Since then and with the help of chairman Nicola Cortese, Pochettino has been able to recruit the type of player he believes can take the south-coast club to the next level, with defender Dejan Lovren and midfielder Victor Wanyama added to the squad at a reported combined cost of over £20million.
Pochettino reckons those additions can help him deliver a successful season for Southampton fans but refused to rule out bringing in more fresh faces before the transfer window closes.
"I'm very happy with the support the owners have given me," he said.
"I'm very happy with the work that Nicola has done and the signings that have been made. Hopefully they will enable us to achieve the goals that we want to achieve for the club.
"I'm satisfied with the players we have in the squad - I'm happy how they have performed in pre-season but if there is anyone out there who can make us better in general then they would be welcomed in to the squad.
"We've very cautious with our work and there has always been a very good communication between me and Nicola when we have made decisions about buying players.
"It is clear there are some weeks left in the transfer window and we might be looking at a couple more players but again we will be keeping that in private."
Cortese has always been an ambitious owner and his financial clout has enabled Saints to build a squad of talented players with Pochettino believing anything is possible in the coming season.
"I think the sky is the limit," he added.
"We can't really set ourselves any limits, we have to think positive and be ambitious. We need to think that we need to win every single game and that every game is a final.
"We will go out looking to win on Saturday and the game after that and the game after that."
Southampton start their campaign with a trip to West Brom at the weekend, having lost on both occasions against the Baggies last year.
Adkins was still in charge when West Brom won 2-0 at the Hawthorns but Pochettino saw his side hammered 3-0 at home by Steve Clarke's side although the former Espanyol boss is not letting that bother him.
"Every game is different, they are really different when you go from one season to the next," he said.
"There are different players with us and with them and I'm the type of manager who learns from every single game I'm involved in. We learned a lot from the games last season against them and we will use them this time.
"It is the first game of the season and that makes it extra special, we all start from zero points and it will be a very demanding game, very intense and very physical."
Pochettino refuted suggestions the Southampton squad and their style of play is now more closely linked to his own approach and was happy to take the rough with the smooth as soon as he was appointed as Adkins' successor in January.
"From the first day I sat here at Southampton it was my team and my responsibility and I was dedicated to this team - it was my team from the first moment I sat here," he added.
"I'm not the type of manager that makes up excuses or boasts when the team is playing well.
"I always take responsibility for my team and my players. It is clear to me that every single manager has their own style, their own brand of football.
"Little details are tweaked and little things are changed and perhaps some tactical solutions are made during games. These are little things that we have worked on in pre-season but our general style of football will be the same."
