Harry Redknapp aims to sign players in their 'prime' in the summer rather than youngsters with potential.
Tottenham have previously invested in the likes of Kevin-Prince Boateng and Giovani dos Santos, who were both rated as extremely bright prospects for the future.
Neither player was able to hold down a regular starting role at White Hart Lane and they have spent time out on loan this season.
Redknapp is now planning to change the club's transfer policy and bring in more experienced players who are capable of making an instant impact.
Spurs have had a promising second half to the season but Redknapp is already considering which areas he needs to strengthen.
"You have to keep moving forward," said the manager.
"I just want players who can come in and make us a better team.
"The players that I have in mind are playing very well and are in their prime."
Redknapp is confident that Spurs will improve next season if he can land the transfer targets he has in mind, with the experienced tactician set to meet chairman Daniel Levy in the next few days.
"I'll sit down with the chairman this week and have a chat and see where we go," he explained.
"I've got one or two people I'd like to bring in, whether we can get them I don't know.
"If we could get the couple of players I'd like I think we'd be a good side next year."
