Tottenham boss Mauricio Pochettino remains patient over transfers and says: “We always spend at the end of the window.”

Speaking to Sky Sports at today’s Premier League launch Pochettino reiterated his aim to only add players to his squad who can challenge his first XI.

Spurs, who have sold Kyle Walker to Man City, are the only Premier League club yet to make a summer signing as they prepare for Sunday’s Premier League opener at Newcastle.

Pochettino though is of the belief that the club will make quality additions later in the month.

“We need players who can challenge our starting XI, players who believe in themselves and think: ‘OK, I can challenge Dele Alli, I can challenge Harry Kane,” said Pochettino.

“Harry Kane knows very well from when he was behind [Roberto] Soldado and [Emmanuel] Adebayor what happens when you’re not focused for a moment, if another player is behind you pushing for a chance if you don’t give your best.

“You cannot guarantee that they [new signings] will play, but you can guarantee the tools to challenge our current players. If they are better and they deserve to play, they will play.”

“If you look at the history of Tottenham in the last few years, we always spend at the end of the window.

“Chairman Daniel Levy is working hard with the chief scout [Steve Hitchen], we are working hard to deliver and try to add the strength we need to fight in four competitions next season.

“It’s not an easy job,” added Pochettino, who remains confident the club will recruit wisely. “We will find the right players to challenge.”
