Pochettino led Spurs to second place behind Chelsea in the Premier League last season
Tottenham have been slow to make summer signings because their "circumstances are different to other clubs", says manager Mauricio Pochettino.
Amid concerns over a lack of transfer activity, the Argentine said Spurs are "working hard to deliver our plan".
"It's not easy to find the right profile but I'm sure we'll add some players in the next few weeks," Pochettino told BBC Radio 5 live.
"We have until the end of the window to try to add more quality and options."
In an interview published in the Sun on Thursday, Spurs full-back Danny Rose questioned why the squad had not been strengthened since the end of last season when Tottenham finished second in the Premier League.
Rose, who joined from Leeds in 2007, said he would "love to see two or three well-known players" arrive, adding: "And not players you have to Google and say 'Who's that?"
He also said he would consider moving "back up north" but specified: "I'm not saying I want out, but if something came to me that was concrete, I'd have no qualms about voicing my opinions to anyone at the club."
