Spurs secured their place in Europe’s elite club competition for the third year running in a season where they played their home games at Wembley, while all the other teams around them spent a huge amount of money.
They could finish third if they beat Leicester on Sunday in their final league game at the national stadium and Pochettino will enjoy their success before plotting a Premier League title challenge for 2018-19.
“Last season, we finished second but it is not enough because we didn’t win the Premier League,” the boss said.
“And this season, again, despite playing at Wembley and many things from the beginning, still (for) some the situation is that, ‘Oh yes, but the team needs to win some titles…’
“Yes, after four years we never celebrate. I am going to celebrate with my people.
“I am going to celebrate with my staff, Jesus (Perez), because I think for us it is a massive achievement and of course not enough – because we want to win titles.
“I think it is not the only thing in football to win titles, but I think after to win in every single aspect I think this club, these group of players, people working here and the fans deserve to celebrate some trophy.”
To realistically challenge the two Manchester clubs next season Spurs will probably have to spend big, but Pochettino still believes his way can be successful.
“One way is to spend money. Another is what we are doing, to create players, like in the case of Harry Kane, Dele Alli,” he said.
“It’s a different way. I repeat, when we arrived here (the aim) was to be focused in trying to provide the team the discipline, the philosophy to create the platform to be competitive and then work with all the resources the club provides for us and be focused on delivering the best job.
“That is my focus until now.”
Pochettino still has three years on his contract at Spurs and said there was “no point” talking about his future.
“Only you know in football that everything can happen. No one is sure in their job, but I have a three-year contract,” he said.
“Like I told the media in Spain after the game on Wednesday, they asked me about my contract and about what happened at some clubs, I told them, ‘Look, I have a three-year contract and they need to agree with (chairman) Daniel (Levy).
“I don’t know, but today it is 100 per cent because I have a three-year contract here.
“But tomorrow I don’t know what is going to happen.”
Eric Dier is expected to return from an illness, but Harry Winks is definitely out.
