Spurs set to keep on spending following arrivals of Paulinho and Soldado.
Tottenham director Keith Mills says the club are targeting more summer signings despite having spent over £50m this close season.
Spurs have moved with uncharacteristic swiftness to add Nacer Chadli, Brazil international Paulinho and Roberto Soldado to their squad.
Midfielder Paulinho cost £17m, while Soldado arrived for £26m from cash-strapped Valencia, meaning Spurs have twice broken their transfer record this summer.
The deals have been offset by the departures of Steven Caulker and Clint Dempsey, and Mills says the club are working on more signings.
“We have made some good acquisitions,” the 63-year-old told the London Evening Standard.
“There are others in the pipeline,” he added.
Spain international striker Soldado, 28, is a particularly welcome arrival at White Hart Lane after dismal seasons for both Jermain Defoe and Emmanuel Adebayor last term.
The England star found the net just once in the league after Boxing Day, while Adebayor scored just five domestic goals all season.
Mills admitted that another striker remains high on boss Andre Villas-Boas’ wish-list.
“Strikers are very high on AVB’s list of priorities and Daniel [Levy, the chairman] is trying hard to make sure we have strength up front. It’s a really exciting time to be at the club.”
Villas-Boas led Spurs to a record points total last season and, despite narrowly missing out on Champions League qualification, the Portuguese rebuilt his reputation after a disappointing nine months at Chelsea.
Mills believes Spurs can take advantage of the managerial chances elsewhere in the Premier League to mount a serious top four challenge under the 35-year-old.
“It will take the three new managers at Manchester United, Manchester City and Chelsea — Jose Mourinho’s gone back so he counts as new — a bit of time to settle down. They’ve mostly inherited their squads, the previous managers did things slightly differently and that may just be unsettling enough. We all know that in sport things unwind pretty quickly.
“Tottenham are in a very good place. We’re optimistic this is going to be a good season and I fancy our chances to get one of the four Champions League slots. We’ve got a great manager now.
“He’s [Villas-Boas] done a great job. He is very professional, uses statistics and the technology in a very intelligent and considered way.”
“He has built a lot of confidence and trust with the players. His job is to get the best out of every player and he does it very well.”
Meanwhile, the future of Gareth Bale continues to dominate the headlines and Mills has reiterated the club’s desire to keep the Welshman, who is wanted by Real Madrid.
“We very much want Bale to stay,” he said.
But he admitted it could prove hard to keep the Welshman if he is ‘desperate’ to join Los Blancos.
“If a player is desperate to leave, it’s very difficult to force him to stay. We’ve seen it in other clubs. Even if he has a contract, you can’t force somebody to play for you.”
Mills also conceded that Spurs are currently in a catch-22, desperate to qualify for the Champions League but unable to do so without keeping players like the 24-year-old Welshman.
“That’s precisely the issue,” he says.
“So this summer, we are investing in a great squad and we hope that provides us with Champions League football next year and we start to win trophies, FA Cups. That’s what Tottenham need.”
