A spending spree saw Tottenham bring in seven players last summer, but the club failed to break into the top four as they ended a season that saw Tim Sherwood replace Andre Villas-Boas sixth in the league.
Pochettino took charge from Sherwood following the latter's departure in May, but has yet to make a signing since and is pleased with the squad at his disposal as he looks to implement his philosophy.
"We have a very good, big squad, always we're looking to improve the squad but no big changes, it's possible that we will improve our squad, but not many changes," Pochettino told reporters.
"The last summer, the club made a big effort in the window in the summer. I believe in these players I think we're always looking to improve but we don't expect big changes.
"Our target for the moment is to provide the team with our philosophy, to develop and improve our style, we have an unbelievable squad with unbelievable players and we need to work to get ready for the start of the pre-season.
"We want to provide the team with our philosophy, this is our target for the moment but after we know Tottenham is a big club, always you need to show to play well, and after to need a win because the result is important because it's a big club.
"But after, during the season the target is coming, but we need to get to the start of the season in good condition."
