Mauricio Pochettino lauded Tottenham's achievement after a 1-0 victory over Newcastle United secured their place in next season's Champions League.
A well-taken goal from Harry Kane proved to be the difference between the two sides on a tense night at Wembley, where Spurs found themselves under pressure from a Newcastle side playing with freedom, having already avoided relegation from the Premier League.
The result moved Spurs up to third and put paid to fears of their season ending in failure following a slump in form and set up a season of Champions League football in their new stadium.
"To achieve the top four is a massive achievement," Pochettino told reporters. "I want to congratulate the players first of all and then the staff.
Another season of football to look forward to!! Thank you for your support May 9, 2018
"Massive congratulations and thank you to all the staff because they have been fantastic and have worked so hard for nearly 38 games away from home.
"For the club it is a massive thing to move to the new stadium and play Champions League. It will be another challenge because it will be the same as playing at Wembley. Yes, it will be a fantastic stadium but we need to make it home and we need time."
Pochettino picked out Moussa Sissoko as one of Tottenham's key players in a match where the France international was called upon to show his defensive qualities as often as his creative ones.
"I am so happy and so proud of the players and all of the players," said Pochettino. "For me one of the best today was Moussa Sissoko. I thought he was fantastic.
"It was a difficult game for us. To play with pressure against a team who have freedom and nothing to play for, it can be dangerous.
"They made it difficult. We rushed some decisions and made mistakes."
Rafael Benitez felt his side were hard done by, drawing parallels with his view of Newcastle's 2-0 home defeat to Spurs in August 2017, but picked out midfielder Jonjo Shelvey as the visitors' stand-out player.
"We had 14 attempts against Tottenham at home and two penalties not given. We deserved something," Benitez told Sky Sports.
"Today [Wednesday] we were doing almost everything well against a good team. It is a pity. Tottenham were a bit anxious and we had enough chances to score.
"If we have time on the ball for Jonjo Shelvey he can make things happen. He is a different kind of midfielder. Different types of players give you different options."
