Pochettino says it can “create a mess” for clubs in England.
“That is another point to talk about, to argue that we are at a disadvantage to European clubs because they have 20 days more to operate.
“I think it’s a big advantage for them. It can create a mess in clubs like us, clubs in England,” added Pochettino.
However, the 47-year-old says he is a “happy man” with Tottenham’s summer business.
The Premier League club signed Fulham winger Ryan Sessegnon and Argentina midfielder Giovani Lo Celso from Real Betis, having earlier broken their transfer record on Lyon midfielder Tanguy Ndombele.
“I’m more than happy with my squad after we close the window in England,” added Pochettino.
Meanwhile, Brazilian forward Lucas Moura – who scored a hat-trick in Spurs’ 3-2 Champions League semi-final second-leg victory at Ajax – has signed a one-year contract extension with the club until 2024.
The 26-year-old joined Tottenham from Paris St-Germain in January 2018 and scored 15 goals in 50 appearances last season.
