What It Means: The field by the river Sheaf, one of its five rivers.
Why It's There: a border town where Northumbria met Mercia, made cutlery from the 15th century, steel from the 18th. Like Rome built on seven hills. Unlike Rome they were hard to build on, so one of the literally greenest cities in Europe, with five rivers running through it.
Why They're There: like Boro, cricketers keeping fit in winter, who played during Wednesday half-day closing. The Wednesday CC dates from 1820; The Wednesday FC from 1867, but the Sheffield wasn't added until 1929.
When It All Began: December 1899, Boro's first Christmas league game, and not a merry one - Wednesday won 2-1. In the FA Cup just one meeting on Teesside, 1-1 (January 1912) - Wednesday won the replay 2-1.
High Point: four titles, twice in succession, 1903 & 1904, 1929 & 1930; three FA Cups, the last in 1935, and the 1991 League Cup; beating United in the 1993 FA Cup semi-final at Wembley, to promotion in 2012 but above all the 4-0 Boxing Day Massacre of 1979 before the Third Division’s record crowd, 49,309, immortalised in song ever since to the tune of Mary’s Boy Child.
Low Point: dropping into Division Three in 1975, and taking five years to get out of it - and another four there since; April 15th 1989, still not resolved, with murky details still emerging, about the police, but people then running the city and the club.
Local Heroes: Arthur Dickinson, 29 years as manager (in Boro terms Bruce Rioch would have just taken over), Robert Brown (13 years and the last to win the title, 86 years ago), Derek Dooley, Nigel Pearson (lifted their only major trophy in last 80 years, the 1990 League Cup), John Sheridan (scored the goal that won it), Chris Waddle, David Hirst, Ron Springett; Milan Mandaric, saved them from winding-up in 2010, buying the club for £1, but got some of the debt back when he sold it for £37m. And (for the moment) the man he sold it to, Thai tinned tuna tycoon Dejphon Chansiri, who wanted "the Premier League by 2017."
Local Villains: Peter Swan, Bronco Lane, Tony Kay, the biggest names in the 60's bribes scandal (Kay, who'd just left for Everton, would have been in the World Cup squad, meaning either Alan Ball and Martin Peters wouldn't); Sheffield United, but like in Liverpool or Nottingham a family-friendly friction; as everywhere in Yorkshire Leeds, especially Eric Cantona, who walked out on Wednesday to join them; Hafiz Mammadov, Azerbaijani who exchanged contracts to buy the club then failed to come up with the money.
Boro Highs: 8-0 (April 1974), 6-1 (April 1908), 5-0 (April 1936).
Boro Lows: 2-3 (August 2014), 0-2 (January 1991), 0-1 (October 1988), Wednesday's only wins since 1934. The other six were all before the First World War, including the two worst, 1-3 (September 1904 & September 1906) .
Hello to: Walter Auld (January 1951), John Craggs (August 1971), Kelham O"Hanlon (January 1983), Chris Freestone & Andy Campbell (April 1996), Gianluca Festa (January 1997).
Goodbye to: Jan-Aage Fjortoft (January 1997), John Brownlie (January 1983); but for two sub cameos, Justin Hoyte (August 2013); Diego Fabbrini (December 2015).
The Floodgates Open: January 1910, 20 year-old George Elliott scores the first of his 213 goals; September 1925, Jim McClelland gets the first of his 48 in 85 games;
And Slammed Shut: Freestone and Auld both scored on their debut, but both started just one more game. Festa scored then hit a post, but stayed for 171 games. Cristhian Stuani scored after 44 seconds in December 2015; no-one scored in the following 89 minutes, and he didn’t again until the final game with Brighton.
Boro Hero: George Camsell (April 1936) four goals in 5-0; George Elliott (March 1914), hat-trick in 5-2; Graeme Souness (April 1974), first and only hat-trick in 8-0; Emerson (January 1997), Paul Pogba meets Jonah Lomu; Andy Campbell (March 2000), only goal of the game, and the only league one he ever scored when Boro didn't lose. Bernie Slaven (December 1989), hat-trick in 4-1 to set up ZDS semi-final;
Boro Villain: Mark Pembridge, scorer of all three of Wednesday's Premier League goals at the Riverside; the linesman who failed to spot Gary Madine three yards offside as he scored in November 2012; the Boro defence (August 2014) which let in three set-pieces, Atdhe Nuhiu who scored two of them, and Phil Dowd, who refused to give Boro a third penalty in injury time even though it was clearer than the one he'd just given; and two men who could be from a lost Dickens novel, Archie Brash and Fred Spiksley, whose goals ruined Linthorpe Road's first Christmas league game.
Boro Bad Boy: Fabrizio Ravanelli (January 1997), sent off for in-your-face rant at linesman with Boro 3-1 up, and after Craig Hignett had done the same thing two weeks earlier against Chester. One effect was he couldn't take the penalty against Wimbledon a week later which would have kept Boro up. Emerson, on whom Selhurst Park acted like a barber on Samson, missed it.
Typical Boro: 0-1 (November 1988), Mel Sterland's goal was their only shot, and the only match manager Peter Eustace (father of ephemeral Boro loanee John) ever won in his four months in the job. It also kept Wednesday up and sent Boro down.
The Other Typical Boro: January 1997, with one win in 16 games and a day after the three points were deducted, Steve Gibson reads the riot act to the players, who produce one of the performances of the season to win 4-2, the only defeat in 20 games for a Wednesday side heading for Europe. Some of it was said to have striking similarities to Ravanelli’s with the linesman.
The Curse of Boro: Wednesday lost the 1966 FA Cup final after dropping their centre-half, who left in disgust, one John Hickton. Hickton scored in all four of his games against Wednesday at Ayresome Park, all of which Boro won, culminating in the 8-0 in 1974; South Bank left-back Ted Cattlin joined Wednesday instead of Boro, won five England caps and the FA Cup, but never scored - except in April 1937 at Ayresome Park, past his own keeper as Boro won 2-0.
Unexpected Item in Bagging Area: Justin Hoyte (November 2012), stunning outside of the foot solo goal, totally opposite to his only other one, a mis-hit cross on a windy day at Barnsley.
Nearly Boro: got to League Cup and FA Cup finals the same season in 1993 - and lost both, one after a replay. Ideal preparation for Nigel Pearson and Viv Anderson, except they didn’t get relegated as well .
The Ghost Goal: October 1998, Mikkel Beck scores twice in 4-0 win, then has a third goal ruled out, but referee Rob Harris and the Boro players take so long to see the offside flag that news is sent round the world. Many didn't realise until after the game, some never corrected it. One national radio reporter had to watch Match of the Day before admitting it. The betting industry went into meltdown, as did Wednesday - they didn't score for four games or win for seven.
Omen Corner: Boro had Sunday’s referee David Coote for their only other cup tie this season when they went out to another Championship team, Fulham. But he also refereed Boro’s last game against Wednesday, a year ago last week, when they won 1-0 at the Riverside. And Wednesday defender Glen Loovens was part of the last FA Cup giant-killing at the Riverside, in the Cardiff defence in 2008. And if Jordan Rhodes finally gets a goal at the Riverside, against who better than someone trained by his Dad Andy, Wednesday’s goalkeeping coach?
Your Boys Took One Hell of a Beating: Jarvis Cocker, Richard Hawley, all four Arctic Monkeys and various Def Leppards, Radiohead's Jonny Greenwood, who has a giant Wednesday Till I Die sticker on his guitar; Michael Vaughan, who once got Hartlepool into Wisden by declaring against Bangladesh in 2005 so he could watch them play - against Wednesday in the League One Play Off final. And, as ever, the unexpected American, this time Jermaine Jackson, a fan since the 1980’s, and who even re-wrote a song for this year's Play Off final against Hull. After beating Brighton he tweeted that Owls were always wiser than Seagulls. But then Tigers have that little more bite than Owls.
