Chelsea and Tottenham go into the last two games of the season knowing that their futures are not set. Incredibly, either could still take the last Champions League spot.
This is a stunning turnaround from the situation a month ago, when Spurs were eight points ahead of their London rivals.
Sportsmail has taken a look at the position both teams find themselves in ahead of the last two matches of the Premier League season.
What are the permutations?
For Tottenham it is simple — win their last two games and they will have secured a place in the Champions League for next season. They could even finish second if Manchester United slip up badly over their final two games.
But if Spurs win only one of the two games against Newcastle and Leicester, or draw both of them, the situation is opened up for Chelsea.
Chelsea have two games to play — against Huddersfield and away against Newcastle — and victories in both of those, if Spurs struggle, would put them in the top four.
Antonio Conte's side could even catch Liverpool if they contrived to lose the game against Brighton at Anfield.
If Spurs do win and draw though, the goal difference gap should be enough that they retain fourth place.
Wait, what in the world has happened over the last month?
Yes — this seemed exceptionally unlikely when Christian Eriksen smashed the ball in from 35 yards at Stamford Bridge. It got even less so when Dele Alli struck twice to secure the win.
Conte and Chelsea seemed to have run out of any hope. Spurs looked like they were on a comfortable stroll to another season in the Champions League.
Unfortunately for them, they have only won one game in the Premier League since, a 2-0 victory against Watford at the end of April.
Damagingly, they were beaten by West Brom in the last minute of their game at the weekend.
That means the gap between Spurs and Chelsea is now only two points.
What's changed at Chelsea?
Conte has made a very sensible tactical switch and swapped out a player out of form for one that can be easily relied on.
Olivier Giroud is among the more unheralded strikers in Premier League history. But the France international generally brings goals whenever he makes an appearance.
It was no surprise to see him score after starting against Liverpool. He was selected for that game, with Eden Hazard behind him.
The two players linked up well, better than Chelsea's other forward options have done at various points this season.
Alvaro Morata's form has been poor, and beyond Giroud and the Spain international, Chelsea do not have another option who can hold the ball up. Giroud's involvement is therefore key.
It is no surprise that Chelsea have won the last three games in the Premier League, all of which Giroud started. He also had a telling impact when coming on as a substitute in the turnaround win against Southampton.
Conte also turned to N'Golo Kante, Cesc Fabregas and Tiemoue Bakayoko as a midfield three. That proves his team with more solidity through the middle and creativity in the form of Fabregas.
The switches mean Chelsea have not lost since that game against Spurs.
Why have Spurs been so poor?
It's hard to put a finger on it. Mauricio Pochettino has generally named his best possible starting line-up for each of the games, the players that have got this team to that point.
One issue is that they have generally come up against teams fighting for their lives — Brighton and West Brom — or one looking to rebound and secure the title in Manchester City.
Harry Kane was out of form, but he scored against Watford, so that's no major excuse. He did still look a little bit less than perfect against the Baggies.
It may also be of note that Spurs have only won once since Kane took the goal against Stoke.
What's Spurs' record like against Leicester and Newcastle?
Against Leicester it is not terrible. They have played six games against them over the last three seasons and won two, lost two and drawn two.
Spurs were beaten by the Foxes earlier this campaign, and they have not beaten them at home since March 2015.
Their form is also up and down against Newcastle. Since the start of the 2014-15 season they have played six games — including one League Cup tie — and have won three and lost three. They did not win either of the home games.
Famously they were also thrashed 5-1 by an already relegated Newcastle at the end of 2015-16.
But they did beat them 2-0 this season at St. James' Park.
Aren't Newcastle — especially at home — a bogey team for Chelsea?
Absolutely — their record there over the last five years is atrocious. They have not won at St. James' Park since December 2011.
That includes three defeats and being held to a draw back in September 2015.
It is worth noting ahead of their visit there on the last day of the season.
What is Antonio Conte's future?
This is the big question for Chelsea heading into the summer. It has been assumed that Conte would leave — and to no real surprise given how their title defence has gone.
But a place in the Champions League and an FA Cup win could change things for the Italian manager.
Roman Abramovich has always been a bit itchy with his trigger finger, yet there would not be much of a desire to dismiss one of the more tactically astute coaches in the world without good reason come the end of May.
