Mauricio Pochettino believes Tottenham can be competitive this season if the players "are thinking in a collective target".
Spurs failed to do any business – either incomings or outgoings – during the summer and they will begin the new campaign with the same squad that finished last season.
It was at the end of the last campaign that, after guiding Spurs to a third successive top three finish, Pochettino challenged Daniel Levy to match his own ambition.
Most people took that to mean the Argentinian, who signed a new five-year contract after issuing his apparent ultimatum, wanted financial backing to bring new players in, but that has not materialised.
What Spurs have done is tie down a number of their key men, such as Harry Kane, Son Heung-Min and Davinson Sanchez to new deals – with more expected to follow suit.
Pochettino insists that to keep his best players when the club are spending £1billion on a new stadium and redeveloping their training ground is being "brave".
And he remains happy with the club's vision despite the lack of arrivals as he added: "I don't feel the panic in football. Some people make a drama in football and drama for me is another thing.
"Football is a game where you need to be clever in how you set your principles, your strategy to try to win the games. Never a drama."
"I think we have a very competitive squad, of course that we are hoping to improve, but if you cannot improve the most important thing is trying to keep your best team, your best players," he added.
"We try to be competitive. It is important to be professional, to have commitment, with the team, with the club, with yourself, full commitment until the end.
"If all the players today are thinking in a collective target, we can be competitive. If we have all the squad thinking as individuals rather than as a collective, you cannot achieve what you want and cannot succeed. That is the key this season."
