Mauricio Pochettino says he is unconcerned by Tottenham's lack of transfer activity, stating that the club are having to make their moves during this condensed period between the World Cup and the early deadline while stressing the desire to avoid "rash decisions."

Last season, the Argentine expressed his hope that deals would be completed earlier this summer, allowing him to work with new recruits throughout the preseason.

But instead, for the second successive summer, Spurs have started their warmup matches in the United States without any new players -- and they have also been unable to sell unwanted men like Vincent Janssen.

With the transfer window closing on Aug. 9 this year, before the Premier League campaign kicks off, the north Londoners have just over two weeks to add players to their squad.

But Pochettino insists he is not fretting about the situation.

"No, like all season we are focusing on trying to improve the team, developing our players and focusing our players," he said. "That is most important.

"We're working hard trying to improve the squad. It's a market has only started to move very quickly after the World Cup, and then this season the transfer window closes on Aug. 9.

"Be sure that we are going to do some movement but, like always, we're working hard -- no rash decisions.

"I'm not worried. I'm happy preparing the team to arrive in the best condition for the first Premier League game.

"And, of course, I'm very happy about the players who have signed new contracts like Harry Kane, [Heung-Min] Son, [Erik] Lamela, Davinson [Sanchez] and Michel Vorm. That's like signing five new players."
