Sunderland stand on the verge of yet another great escape and one which would force North East rivals Newcastle out of the Premier League.
The Black Cats' 3-2 victory over Chelsea, coupled with the Magpies' 0-0 draw at relegated Aston Villa and Norwich's 1-0 home defeat to Manchester United, means Newcastle will be relegated if Sam Allardyce's men beat Everton on Wednesday evening.
Here, we look at their derby rivalry.
Best of enemies
There have been a total of 144 Tyne-Wear league derbies and Newcastle just edge it in terms of wins, with 51 to Sunderland's 48 and 45 draws. The Magpies had the better of the fixture during the early part of the 21st century but the Black Cats had won six on the trot before a 1-1 draw at St James' Park on March 20.
Premier League record
Newcastle have spent far too much time in the wrong half of the Premier League table since finishing fifth in 2011-12, while Sunderland are battling the drop for the fourth time in as many seasons. These are their respective finishing positions for the last five campaigns:
Newcastle: 12th, 5th, 16th, 10th, 15th.
Sunderland: 10th, 13th, 17th, 14th, 16th.
Newcastle are unbeaten in five games, but could not win at Villa when they needed it most. The Black Cats have lost only once in nine games, but were struggling to win before their priceless victory over Chelsea.
It has proved a huge source of frustration to fans that under owner Mike Ashley, Newcastle have become a profitable club. The Magpies' latest official figures showed a profit of £32.4 million, an increase of £13.7 million, although they have spent heavily on player recruitment since and the club owes Ashley £129 million in interest-free loans.
By contrast, Sunderland last week reported an operating loss of £25.5 million, an increase of £9.2 million on the previous year, and remain indebted to owner Ellis Short for his continued support.
The one thing both clubs can boast is remarkable support given their current plights. Newcastle had a sell-out crowd of 52,107 for their most recent home game, a 1-0 victory over Crystal Palace, while a full house of 47,050 watched Sunderland's win against Chelsea.
