Tottenham secured Premier League survival on a dramatic final day of the season on Sunday as West Ham's 14-year stay in the top division came to an end.
Spurs kicked off against Everton needing, realistically, only a draw to avoid relegation for the first time since 1977 - as they sat two points clear of the Hammers with a significantly better goal difference.
Joao Palhinha released the mounting pressure at the Tottenham Hotspur Stadium just before halftime, poking home after his header thundered back off a post.
The Portugal midfielder was mobbed by his teammates as head coach Roberto De Zerbi sprinted down the touchline, turning to celebrate with ecstatic fans in the London sunshine.
That goal left Nuno Espirito Santo's West Ham, then drawing 0-0 with Leeds, needing a favor from Everton, even if they went on to win their match.
Just a few miles away, at the London Stadium, Valentin Castellanos gave West Ham some hope midway through the second half as he fired the Irons in front.
Jarrod Bowen and Callum Wilson made it 3-0 at the full-time whistle but it was too little too late for the Hammers as a nervy Spurs held on to secure all three points.
Spurs have enjoyed a mini-revival in recent weeks under De Zerbi, who arrived in late March as the club's third manager of the season.
Relegation would have been financially disastrous for the ninth-richest club in the world, who won the Europa League last season under former boss Ange Postecoglou.
"It's an amazing feeling after a really tough season," Palhinha told Sky Sports after the match. "A lot of things happened this season but we showed today what we can do. After a bad season like this one we showed up as a collective and had amazing support from the fans.
"The club will grow up with this season and we know what we have to do in the future. It's a big pleasure to play here with a top coach and top teammates. We have to celebrate even if we didn't finish in the position we deserve as Tottenham."
The Hammers, who were promoted to the English top division in 2012, will join Burnley and Wolves in the Championship next season.
