It's no easy feat for Mauricio Pochettino and Spurs recruitment team, which perhaps explains why Spurs have endured a quiet start to the summer.
A disappointing display in the UEFA Champions League needs to be eradicated too, especially with another season at Wembley ahead. The north London club must do better while making sure they are definitely in the hunt for a place in the top four.
Despite being linked with a number of high profile names, including Arsenal transfer target Thomas Lemar and Celtic's most-wanted striker Moussa Dembélé, no signings have been completed. But it is only a matter of time, however, until Spurs launch into action.
We take a look at the top five Tottenham transfer targets according to the Football Whispers Index — which scores the validity of transfer rumours out of five — to see who could help Spurs in their title quest this season.
JUAN FOYTH – ESTUDIANTES – 3.7
The 19-year-old only made the jump up to the club's first-team in January 2017 and went on to make four appearances last season.
That was enough, however, to be included in Argentina's squad for this summer's FIFA Under-20 World Cup and he made an appearance in a 3-0 defeat to England.
Former Manchester Untied and Chelsea midfielder Juan Sebastian Veron, the Estudiantes president, is due to fly to London from Italy this week to undergo talks regarding the move.
Toby Alderweireld and Jan Vertonghen are 28 and 30 years old respectively and it would make sense for Spurs to look to the future. The young Argentine defender could benefit greatly from working with his countryman.
JOSH KING – BOURNEMOUTH – 3.0
Back in June, Josh King told the Bournemouth Echo that he was intrigued with the possibility of a move to Spurs. But added he wasn't going to leave the Cherries in a hurry.
“I was intrigued even being mentioned in the same sentence as Spurs, a big team who play in the Champions League,” said the 25-year-old. “It is the summer holiday now and I've learned so much from the gaffer here.”
“You never know in football but, hopefully, I will be here next year and I'm looking forward to working with the gaffer because he's been brilliant with me since the day I set foot on the training ground.”
Spurs are in the market for a striker to play a back-up role to Harry Kane and although they are not going to dump Vincent Janssen after just one season, Pochettino needs more options in attack.
After 16 goals in the Premier League last term, the Norway international is a hot commodity but, as reported by The Mirror, King doesn't want to jump ship and join a side where he has to play second fiddle.
For Tottenham, it's a move that would make sense, but they would have to convince the player that Champions League football is enough to make up for not starting every game.
ROSS BARKLEY – EVERTON – 2.5
News that Everton had made a £32million bid for Swansea midfielder Gylfi Sigurdsson suggested one thing; Ross Barkley's time at Goodison Park is almost up.
The arrival of Wayne Rooney plus Davy Klaassen's signing from Ajax will limit the options in attack for a player like Barkley.
SunSport revealed last week Spurs are interested in signing the 23-year-old this summer, but not for the reported £50million asking price.
But once the Toffees receive £75million from Manchester United for Romelu Lukaku, they might soften their stance on how much they want for the England international.
Barkley would certainly fit into Pochettino's midfield as he's able to play any of the central roles, but he can also slot in behind Harry Kane if Dele Alli or Christian Eriksen were out injured.
There is definitely untapped potential in the player and the Argentine boss would hope to unleash his full ability. Barkley has scored 21 goals and added 21 assists in 150 Premier League appearances, that could be exactly what Spurs need to sustain a title challenge.
SERGE AURIER – PSG – 2.4
Reports in France suggest Manchester City transfer target Dani Alves.
And with two right-backs already at the Parisian club, it would suggest someone is on the way out. That may be the window Spurs need to pounce for Serge Aurier.
Thomas Meunier impressed for PSG last term so it seems Aurier's time in the capital is up. Spurs may be front of the queue but Juventus are also looking to make a move for the 24-year-old if PSG are willing to sell.
PSG were looking for a replacement before agreeing any deal for the Ivorian, and signing Dani Alves on a free would make it possible.
Aurier offers everything that Spurs fans love about Walker. He is a willing runner, able to break down the channel and fire in dangerous crosses. He is a good defender too and has the strength and aerial ability to play at centre-back.
The player was refused a visa for entry into the UK when PSG took on Arsenal in the Champions League last season due to ongoing issues with the law but a permanent transfer should see those problems resolved and shouldn't have any impact on a transfer.
JOSÉ GIMÉNEZ – ATLETICO MADRID – 2.2
Good defenders are hard to find so when one reveals he hopes to play in the English top flight, ears around the top clubs begin to twitch.
“I dream about playing in the Premier League because all the games are pretty even,” the Uruguay international said, but he did offer a pretty huge caveat to making such a move. “But if Atletico make a contract for life, I am staying.”
“Atletico have taught me so much since the day I arrived. I'm privileged to be at the club. I'm calm about transfer rumours and I always discuss them with my representatives.”
The 22-year-old is in the early stages of his career but he would have been unhappy to only play 17 games in La Liga last term.
Able to play at centre-back and right-back, he was behind Diego Godin and Stefan Savic last season.
But with Godin now 31 years old, Giménez may find more minutes by staying in Spain – especially as he is not going to displace Vertonghen or Alderweireld anytime soon.
