Spurs are the only Premier League club yet to sign a player this summer having spent around £100million on seven players last year in a bid to offset the sale of Gareth Bale to Real Madrid.
Not all of those signings paid off, with Roberto Soldado and Erik Lamela in particular enduring difficult first campaigns in England, but Pochettino hopes they will benefit from that experience and is happy with the players at his disposal.
When asked about incomings to White Hart Lane, he said: "Not many. We have a very good and big squad. Last summer the club made a big effort during the window and I believe in these players. We are always looking to improve but we don't expect big change."
Speaking ahead of Spurs' first pre-season game against Seattle on Saturday night, the former Southampton boss said his initial task is to establish a playing philosophy at the club.
"It's a different club to Southampton. Tottenham is a bigger club and we need to win, but not only win, we need to create a good philosophy. Our philosophy is exciting football, pressing attacking football.
"This is our target for the moment. During the season the targets will come."
