In fairness, we had created the better chances and Roy Carroll had made all the saves - Giles Barnes missed Derby's best chance, prodding a one-on-one wide in the first chance - but once Robbie Keane opened the scoring after 68 minutes there was only one winner.
Younes Kaboul doubled our tally after 81 minutes before Dimitar Berbatov slotted home a penalty in injury time.
"I think we competed very well, but they are better footballers than us," said Jewell. "Technically they are better than us.
"For the first hour I think we had them rattled but once the first goal goes in they look like a different team - and so did we.
"They have a wealth of talent on the bench too. That is why we are bottom of the league, because we can't compete at the level Tottenham are at right now as far as looking for players is concerned and ability.
"But hopefully in a few years, with the help of the takeover, we will be able to because I believe this club is big enough.
"We might have to take a step backwards to go forward, but I believe we will be able to compete."
Paul Jewell was pleased with Derby's first hour at Pride Park - conceding that first goal made all the difference.
