Mauricio Pochettino will ask Spurs to match his ambitions with money when he meets chairman Daniel Levy.
The manager wants the club to "take risks" in order to win trophies and the Argentine is known to have suitors elsewhere, with Real Madrid repeatedly linked to him, leaving Pochettino in a strong position.
Spurs have qualified for the Champions League once again but failed to challenge for anywhere silverware, leaving Pochettino in no doubt how things should improve.
Pochettino's comments came after witnessing his side win their final game of the season 5-4 against Leicester City.
"I don't know if the club will be agreeing with me or not, but we are going to talk, next week on what we need to do to improve," said Pochettino.
"That is a little bit up to Daniel (Levy) of course, to the club, to be happy with us, because after four years I think we need to assess that period.
"If we want to play and be real contenders for big, big trophies, yes, we need to review a little.
"I think Daniel is going to listen to me. But you know me and sometimes I have some crazy ideas.
"But you need to be brave. In this type of situation, with a club with our unbelievable fans, being brave is the most important, and to take risks.
"I think it's a moment the club needs to take risks and if possible work harder than the previous season to be competitive again."
