Mauricio Pochettino sends message to Daniel Levy over Tottenham spending ahead of talks
Spurs can secure their place in the top four by beating Bournemouth but Pochettino admits something may have to change
Mauricio Pochettino has claimed Tottenham "cannot live like we lived in the last five years" before talks with Daniel Levy over the future of the club.
And the Argentine insisted they cannot suffer another "negative" start to next season.
"We need to fight for big things, behave like a big club and do things properly," he said.
Spurs can seal Champions League qualification for the fourth consecutive year with victory at Bournemouth .
And the North London club will then play the second leg of the semi-final against Ajax.
The Argentine boss said Spurs have "overachieved maybe" - especially in a season where they spent no money in two transfer windows as they finally moved into the new White Hart Lane after long delays.

When the new £1bn arena opened last month, Pochettino revealed he will hold talks with chairman Daniel Levy to discuss the next stage of the project.
And asked if this season could be repeated, the Tottenham manager said: "I cannot guess. When we finish the season I think it's a moment to close a five-year chapter, to analyse, to talk a lot and to give the real value of that period.
"It was amazing. The problem is, what do we want for the next chapter of the club? Now we've finished the training ground, finished the stadium.
"What does the club want to achieve in the next one, two, three or five years and what are the fans going to expect from the club? There's many things to talk about and put on the table, and then try to be realistic.

"We cannot live like we lived in the last five years – on the perception side and on the reality side. We achieved a lot of things. We overachieved maybe. But what next?
"I cannot guess. Because it's a club decision and talk. What can we expect now? One question the other day was 'the depth of the squad is not at the quality of the new stadium' in a press conference.
"If we start next season talking about that, nothing good is going to happen in the future. The perception and the feeling are not going to be right. We need too much.

"The expectation, the reality – and then, of course, we need to give you [the media] the tools to provide our fans with the reality and find a good balance.
"We cannot sell to our fans negative things. We must always be positive. But sometimes if it's too positive, we create an expectation that's not the reality. And maybe I'm bored of talking about that.
"But that's the reality. We need to fight for big things, behave like a big club and do things properly."
