Tottenham spent money on Serge Aurier, Fernando Llorente, Davinson Sanchez and Juan Foyth this summer, but sold Kyle Walker to Manchester City.
While this does not exactly class as a low-spending window in relative terms, Spurs boss Pochettino has today pointed to the fact that, unlike certain other Premier League clubs, the North Londoners simply can't afford to bring in whoever they want.
Manchester City and their manager Pep Guardiola spent around £220 million on a massive squad overhaul while Jose Mourinho and Manchester United spent £150m on Romelu Lukaku, Nemanja Matic and Victor Lindelof this season.
And Pochettino insists the club have little choice but to conduct themselves differently in the transfer market compared to their rivals.
"The difference these days between clubs in the Premier League is that there are clubs, like City and United, who sign who they want and when they want", he told beIN Sports, Goal report.
Tottenham sit five points adrift of both Manchester clubs, who are tied at the summit of the Premier League on 19 points after seven games.
