Juande Ramos insists he will have no hesitation in dropping his big-name stars if they continue to falter.
Tottenham were tipped to mount a top four challenge this season, but currently prop up the Premier League table after taking just two points from their opening five fixtures.
A dire goalless draw with Wigan on Sunday has seen the pressure mount on Ramos as the club shows no sign of shaking off the shackles which have hindered their progress.
The Spaniard withdrew summer recruits Roman Pavlyuchenko and David Bentley as he sought a solution to the ongoing problems, and admits he will continue to tinker if results do not drastically improve.
"It was not because of a slight ankle injury that I substituted him (Pavlyuchenko)," said Ramos.
"Some of the players we have brought in just before the close of the (transfer) window need time for adaptation and preparation.
"They will get it but if they play and it is not going well I will look for something different, a different way to win a game.
"They know it has been a difficult start but that's normal in this situation. We have had a lot of changes and it will not be easy or quick to make things work perfectly.
"We have to just keep working hard together and I hope the Carling Cup competition will lift the players because it is a special thing for the club.
"This game with Newcastle (in the third round on Wednesday) is one we want to win - not just because we have the trophy but because we need a win in a different competition to help us gain confidence in the Premier League."
Ramos has used 21 players in Spurs' six games in all competitions this season, but is yet to find a winning formula.
Jamie O'Hara has been a rare success story after a number of impressive showings, but the 21-year-old admits overall performances thus far have not been good enough.
"The main priority for the team is to get the victory and to get out of this bad start. It's not falling for us at the moment," said the midfielder.
"The lads were really gutted sitting in the dressing room after the Wigan game because we felt we were on top, especially in the second half, and I thought we should have had a penalty awarded.
"But all we can do is pick ourselves up, keep going and try to get the results."
