As Jack Colback becomes one of a handful of footballers to play for both Newcastle and Sunderland, we look back at others who made the move.
On to sport and preparations are well underway for Gateshead's trip to Wembley.
Gateshead FC has sold nearly 7000 tickets for the play off final at Wembley but Heed supporters will be outnumbered by Cambridge United fans
Sunderland AFC have completed the transfer of 24-year-old midfielder Will Buckley on a three-year-deal from Brighton and Hove Albion, for an undisclosed fee.
Buckley made 70 appearances under Gus Poyet at Brighton, scoring 16 goals.
He becomes Sunderland’s seventh summer signing.
Sunderland head coach Gus Poyet has admitted striker Ignacio Scocco's future is likely to lie away from the club.
Scocco, known as "Nacho", arrived on Wearside in January as Poyet invested £3.2million in his services in the search for goals to keep the Black Cats in the Barclays Premier League.
Ultimately, it was a gamble which did not pay off as the 29-year-old Argentinian made only eight appearances and failed to find the back of the net.
French television staff working on the coverage of the Tour de France have set up their own screens in Harrogate - so they can watch France take on Germany in the World Cup quarter-finals.
Middlesbrough's Marvin Emnes has completed a move to Swansea City. The 26-year old Dutchman joins the Welsh club for an undisclosed fee after signing a three-year contract. His departure will come as no surprise to Boro fans, as Emnes has had two previous loan spells at Swansea.
Colin Cooper has made his second signing of the summer for Hartlepool United - the former Middlesbrough man Stuart Parnaby.
The club said Cooper was quick to make his move once he realised Parnaby was a free agent, because he can play anywhere across the back four or in midfield.
Parnaby grew up in County Durham and rose through the youth ranks at Middlesbrough. He was part of the Birmingham City side that beat Arsenal to life the League Cup in 2011.
As England and Liverpool player Jordan Henderson prepares to take his place at the World Cup in Brazil, his old teachers at Farringdon Community Academy in Sunderland are watching.
They remember him for his "fantastic attitude" and use him as an example to other teenagers about what could happen if they work hard.
Simon O'Rourke reports.
He is now an international star, a key figure in Liverpool's midfield and in Brazil expecting to start for England against Italy in the World Cup. But aged 14, Jordan Henderson was an enthusiastic member of the Year 9 team at Farringdon Community Academy in Sunderland. Can you spot him?
Incidentally, that line-up also includes another now international sports star. The boy in the school blazer on the far left is Durham and England cricketer Scott Borthwick.
Sunderland-born Jordan Henderson is expected to be in the starting line-up for England against Italy in the World Cup. He left the Black Cats to join Liverpool in 2011, but has not been forgotten on Wearside.
David Robinson was Henderson's football coach at Farringdon Community Academy and said he always had a "fantastic" attitude.
A coach who has known Jack Colback since he was a child said he should have joined Newcastle United when he was given the chance aged 11.
As a young player with Cramlington Juniors FC, Colback was part of a development programme at Newcastle, but chose Sunderland instead. Now he is moving back to Newcastle, aged 24, causing something of a row with his former club.
Michael Cairns, his coach as a child, said: "He should have signed for Newcastle when he was 11 really but as it happens it's turned out all for the best now so good luck to him."
A spokesman for Sunderland AFC said the club was "dismayed" Jack Colback has agreed a deal with local rivals Newcastle United, saying the move "leaves a bitter taste in the mouth".
"Jack is a player we have nurtured and developed through our academy system since he was eight years old. We gave him the opportunity to become a professional footballer and are therefore extremely disappointed in the events that have led to his departure from the club"
“This wasn’t about money - the club agreed to all of the terms demanded of us during discussions and we were always led to believe that Jack wanted to stay with us. At his and his representatives’ request, final talks were put on hold until the club secured its top flight status.
"To our dismay however, we were subsequently never given the chance to negotiate with him to stay.
“For him to then leave the club that has supported him throughout his formative years in such a manner, with no chance for Sunderland to recover any of the significant investment that it has made in him as a player, has left a bitter taste."
