Antonio Conte says Tottenham would be "foolish" to spend big in the transfer market and will use "common sense."
Spurs have made six signings during the window, landing Richarlison, Yves Bissouma, Ivan Perisic, Djed Spence, Clement Lenglet and Fraser Forster.
The London club have also been linked with Roma attacking midfielder Nicolo Zaniolo and Barcelona forward Memphis Depay, while teenage wing-back Destiny Udogie is expected to arrive form Udinese and return to the Serie A club on loan.
They are also reportedly set to trigger a £41million release clause to make centre-back Cristian Romero's loan move from Atalanta permanent.
Tottenham head coach Conte has vowed there is no chance the club will be reckless before the transfer window closes on September 1.
He said ahead of Sunday's derby at his former club Chelsea: "We improved in this way but I know I can't have everything quickly, it would be foolish to ask for a lot of players and spend a lot of money.
"We're doing the right things with common sense, not to spend the money on many players. Also, this is not the politics of the club, I understand this. We have to go in the right way, doing the right things."
Conte is pleased with the strength of his squad as Spurs look to make further strides after securing fourth place in the Premier League last season to seal a Champions League spot.
The Italian added: "I'm very happy with our squad because, compared to last season, we improved with Richy but we lost [Steven] Bergwijn. [Bryan] Gil went on loan but now he's in the squad of 20 players. I think in midfield we improved with Bissouma and with [Harry] WInks, and then with Lenglet behind.
"We signed players with common sense, to find players with the right characteristics, to help us have the quality. To have reliable players, players ready to have a good impact."
Tottenham will be without defender Lenglet and midfielder Oliver Skipp for their second Premier League game of the season due to an abductor injury and a hairline heel fracture respectively.
