After finishing runners-up to Chelsea in last season's Premier League title race, many would have expected the North London club to invest in their squad, especially with the rest of the top-four contenders splashing the cash.
Spurs have yet to sign one player, despite selling Kyle Walker to Manchester City for around £50million, but they have been linked with Everton's Ross Barkley (5/6 to sign with Sky Bet) and Bournemouth's Josh King (5/2).
Pochettino seems in no rush to bring new recuits in as the club prepares for a home season at Wembley while White Hart Lane is re-developed and feels the club's philosophy to keep faith with the majority of the current squad can pay off.
He told ESPN FC: "Always the philosophy is coming from the board and in the case of Daniel Levy, I think we have a very good relationship, we have a clear idea of what we need to do in the future.
"I think our facilities are amazing and the training ground and the new stadium will be one of the best in Europe. It's an exciting moment for Tottenham. But it is true we have a different philosophy, it's not because we cannot invest, but Tottenham have built a different philosophy than the other big clubs.
"I think in football, money can help you build a better squad or bring in talented players but it's not only about money, you need to be creative, you need to be clever. It will be tough next season for us, but we believe in the way that we play and we work."
On the club's improvement during his time in charge, he added: "I think, after three seasons, the first was really tough for us because when you try to change the philosophy and habits and try to develop a complete opposite way of playing and behaving, it was very tough for us.
"The last two seasons, it is true, we improved a lot. It is very clear, our philosophy is about trying to play exciting football with young players and trying to be different to the top sides. I think next season is a big, big challenge for us.
"For one, it's because we moved to Wembley, a different environment for us, a different pitch and stadium, all will be different for us. It is true that we must change because we were very comfortable playing at White Hart Lane.
"And then, I think because the big sides are investing a lot of money in trying to improve their squads, but for us we are so calm and so quiet because we have belief in our youth from our academy. We may lack a few players, but we are so calm because I think we have a very good team and the most important thing for us always is the team."
