Everton secured their Premier League status as Dominic Calvert-Lewin's 85th-minute header saw them complete a remarkable second-half comeback from two goals down to clinch a 3-2 win over Crystal Palace on a night of high drama and tension at Goodison Park
Frank Lampard's side grabbed their second shot at safety having lost at home to Brentford on Sunday to preserve their top-flight status for a 69th successive season
Everton knew they would avoid a first relegation since 1951 with victory against Patrick Vieira's team on Thursday, but they trailed 2-0 at the break after Jean-Philippe Mateta's opener (21) was added to by Jordan Ayew (36)
Michael Keane's instinctive finish sparked the fightback nine minutes into the second half, and after Richarlison had restored parity with his 10th Premier League goal of the season (75), Calvert-Lewin met Demarai Gray's cross five minutes from time to spark bedlam inside Goodison as fans invaded the pitch to celebrate
There were unsavoury scenes at the full-time whistle as Palace boss 
 The result means Everton move onto 39 points, four clear of Leeds ahead of their visit to Brentford on Sunday
"It's really difficult, I just said that to the players," Frank Lampard said afterwards
 "What we've just seen, it's Premier League safety, it's not Champions League
 But what it means to the club and circumstances they were given in
 The character of this club, the fans, players, just got us through
 The spirit of the club was immense
"There are a lot of people who work so hard for that, the players, the board, the fans, my staff
 It's a huge night for Everton and now we want to take that forward
"Relegation battles are tough and an experience in their own right, the support I've had from the owner, chairman, Denise and what the fans have brought in is hard to do
"Everyone can see the heart and the soul of the team, that's why we stayed up
 When I arrived at the club there were cracks, now it's time to restock and learn
 There's a reason why we're here
"rung around on loop long after the final whistle as fans again entered the field to mob the Everton players
 This ground has seen some great escapes during its time
 It was against Wimbledon on the final day in 1994 when Everton were trailing 2-0 and staring down the barrel of relegation when Barry Horne would inspire a stupendous rescue act
After the chaotic 3-2 loss to Brentford having led twice and been reduced to nine men, Everton's latest shot at redemption started tentatively with Ayew heading wide Tyrick Mitchell's cross on seven minutes
Since Farhad Moshiri started investing into Everton as the club's majority shareholder in February 2016, very few players from the £563m spent have proven an unqualified success, but Richarlison certainly falls into that category
He sought to ease the tension and ignite this contest when his curled free-kick grazed the crossbar via Jack Butland's fingertips, although referee Anthony Taylor awarded a goal-kick
The home crowd's anger turned to anguish moments later as Palace broke the deadlock
 Eberechi Eze's fabulous free-kick from the left was swung in between Abdoulaye Doucoure and the flat-footed Vitalii Mykolenko as Mateta stooped to beat Jordan Pickford
It was the 19th set-piece goal Everton have conceded this season with only Leicester (20) having conceded more
Lampard needed cool heads, but Seamus Coleman led an incensed reaction to a reckless challenge from Ayew on Anthony Gordon on 34 minutes which was met with only a yellow card when the irate home supporters were baying for stiffer punishment
Those groans turned to even darker despondency two minutes later when Ayew doubled Palace's lead in slapstick circumstances
 Coleman lost possession on the halfway line as Mateta raced free down the left to deliver a cross which caused Pickford to only bat the ball out under pressure from Ayew
Wilfried Zaha slammed his shot into the ground as the England goalkeeper rose to divert only into the path of the Ghana forward, who steadied himself to nudge the ball over the line
Everton had offered very few problems, with Andre Gomes' tame dragged shot into the gloves of Butland and a header wide by Richarlison from Mykolenko's cross barely worthy of mention, and a misplaced pass from Coleman under no pressure in first-half stoppage time summed up the malaise that was setting in
Lampard needed the break to re-enforce the instructions his players had failed to carry out, with Dele Alli replacing Gomes prior to the restart
 The mood certainly wasn't made any brighter when news came through that Burnley had taken the lead at Aston Villa, but Keane would restore belief when he halved the deficit nine minutes into the second half
Mykolenko's deep free-kick was kept alive by Mason Holgate and after one touch to steady himself, Keane brilliantly flicked nonchalantly beyond Butland
 It was a lifeline for Everton
News filtered through that Villa had levelled against Burnley as hopes rose a little further for the hosts, Palace looked to slow down the game and yet Everton would restore parity through a moment of quality from Alli
So long maligned, the player bought from Tottenham on deadline day in January controlled Coleman's cross at the far post and show his undoubted class to bring in the onrushing Richarlison for an untidy finish into the ground and beyond Butland as Goodison erupted
Another cross from the right, this time from the substitute Gray veered deliciously away from Marc Guehi and through the noise, time stood still, as Calvert-Lewin launched himself through the air to crash his header into the net
Supporters halted the restart after filling the pitch
 Seven minutes of stoppage time would be added on but there was no stopping Everton
 Elation greeted the final whistle, and another pitch invasion
 Despite the joyous scenes, the over-arching feeling was one of relief more than anything else
This is no cause for celebration, Lampard admitted, but an acceptance of just how perilous the situation had become
Everton boss Frank Lampard: "If you're honest you have to fake it, act a bit
 Not show your feelings
 You have to turn people and inspire them
 Dele Alli came on and was amazing
"My point was it's not the tactical change, it's the emotions and the character
 Can you energise the crowd and score an early goal? Then it's the energy, the players deserve immense credit
"If we don't get that first goal, it's difficult to win
 I expected Burnley to get something
 That goal was crucial, once it went in you felt the players, and the night, there was something special there
 The crowd reacted, we created a special night in Everton's history
"On the fans, Lampard said: "It was so important
 We needed them tonight, at 2-0 it was easy to expect the worst
 But they've been doing it for a long time, since the Chelsea game
 After Burnley was difficult
 Again, the atmosphere was another level, it was great to see them on the pitch
"We don't condone it but it was in such good faith
 They want success and when they see a team giving it they react instantly
 Those moments were priceless
"Crystal Palace have scored nine goals against Everton this season in all competitions, the most goals they've scored against an opponent in a single season since also putting nine past Sheffield Wednesday in 2001-02
But they were unable to secure a third win in the same season - having beaten Everton in the league and FA Cup at Selhurst Park - and Palace boss Vieira said afterwards: "What changed is that we didn't respect the game as we did in the first half
 We've been losing too many simple balls and we were inviting too much pressure
"We allowed them to build a momentum and confidence
 It's about managing the game at 2-0 but we gave them hope
 We invited pressure which woke up the crowd and then they made it difficult for us
"When were 2-0 up, we had the chance to score a third which would've been game over
 But the discipline we had in possession in the first half we didn't show in the second
