Mauricio Pochettino has called on Tottenham chairman Daniel Levy to begin "a new project" as the club prepares to move into their new stadium.

Pochettino said Spurs' breathtaking new home, which will finally open against Crystal Palace on Wednesday, heralded a new chapter and he urged Levy to "operate in a different way".

His comments echoed those he made after the final game of last season, a 5-4 win over Leicester City in what was supposed to be Spurs' final league game at Wembley.

Although Pochettino signed a new five-year contract soon after, the club has gone two transfer windows without a signing, and their net spend under the Argentine – around £40million in nearly six years – and wage bill are considerably lower than their top-six rivals.

Pochettino did not specify what he wanted from Levy but said the club now deserves to be a contender for trophies every season – suggesting he wants the chairman to remove the financial shackles.

"Next season we need to build or be ready for a new project, a new chapter – two years, three years, four years – it depends on Daniel, who is going to decide," the Spurs manager told a press conference at the new stadium.

"I am happy and proud to finish a chapter this season, competing the way we compete, helping the club, the fans, the players to be better. It is another thing to talk and sit here again talking about where the club needs to be in the next level, in the future. We need to close the chapter – it’s been fantastic – and think in the long-term to put Tottenham where they deserve to be."

Asked what this new chapter should look like, Pochettino said: "I don’t know. That is a decision always for the chairman. A new project means to maybe to talk in a different way, to operate in a different way. It was so useful the way that everyone helped the club achieve what we wanted to achieve, being very competitive and aggressive in the way we play.

"It's a stadium to be in every season of the Champions League, every season being a real contender and fighting for big things. It is my idea and we we will see if we can deliver it. That is what the club deserves."

Despite Pochettino's lofty ambitions, Tottenham enter the new era on the back of the worst run of the manager's tenure, having taken one point from the last five matches to leave them in a scrap to finish in the top four.

The last gasp defeat at Liverpool on Sunday, coupled with Arsenal's subsequent win over Newcastle, saw Spurs fall behind their rivals for the first time this season, and out of the top three. However, Pochettino believes playing five of the final seven matches in their new stadium gives his side an edge.

"It must be an advantage, a massive boost for us," he said. "Now we need to feel that our new stadium is our new home. We need to feel comfortable. We have had only one training session, but tomorrow night we must feel well and celebrate not only the party and the opening but also three points which would be massive for us.

"Of course, the best stadium in the world must have the Champions League. It would be a shame to not be in the next Champions League," he added.

"This is a project to be one of the best clubs in the world. We need time but we are going to fight. We are in the top four, disappointed with the last result but of course it's not the same.

"Against Liverpool we deserved more, played really well second half, the feeling was so good. Playing like this I have no doubts we are going to be in the top four and playing Champions League next season. It's in our hands. It’s a mini-league and playing five games in our new stadium will be a big boost for our players and fans. It's up to us to achieve that."

Having spent an additional eight months at Wembley during delays to the stadium, the Palace game – which will be preceded by an opening ceremony – promises to be an immense outpouring of emotion from supporters.

"You cannot stop the atmosphere that feeling that everyone who comes here tomorrow is ready for a party," Pochettino said. "At the same time it's so dangerous. We need to deal with this excitement and energy. We need to spend that energy in the 90 minutes.

"It's impossible to not think you're coming here for a party because it's an opening day, but we need to be focused, to create that atmosphere. The most important thing for the history of the club is to open the stadium but the three points are in the same level, important too. For us we must be focused on three points and Crystal Palace because it's going to be tough game.

"We need to deal with it. This is one of the most important things in the history of the club and we need to understand it is a football game we must win. It is so important for us but at the same time the people are going to be excited about not only the game but one of the best stadiums in the world."
