Sunderland, Newcastle, Leeds, Nottm Forrest....just a few teams I wish were back on the top level. English football is better when these clubs are in the mix. As we all know the commitment of your OWNERSHIP plays a big role in modern football, so hopefully they continue to invest as much as Sunderland fans do every week. Besides the accents, what are some other differences btw Newcastle and Sunderland (the town/people/etc.).
Obviously I am Sunderland supporter I will see things from my teams point of view but will be as objective as possible.
Newcastle as a city as a lot more going for it, it's on the main rail and road links into the north east and is closer to the main airport in the area. It has had millions more in investment spent on it and has a wealth of bars, restaurants and hotels.
Sunderland is poorer there's no doubting that, the city centre is improving but hasn't had anywhere near the same investment. They are both shipbuilding cities although that industry has pretty much died out. They are both working class cities and football is a religion, life for many people revolves around the football team.
I would say Sunderland supporters are more easy going and travelling away supporters get a friendly welcome in Sunderland whereas Newcastle supporters can be more aggressive. We played each other in a lower level cup competition 2 weeks ago and the travelling Newcastle supporters ripped seats out causing quite a bit of damage. I mentioned the police horse being punched which was after a game that we beat them at their ground after which a full on riot took place across the city. There have been several riots in Newcastle after they have had bad results with widespread damage and disorder occurring. In another 'derby game' (When 2 local rivals play each other) Newcastle supporters invaded the pitch to try and get the game abandoned as they were losing. I can honestly say there has never been any of those kind of instances at Sunderland.
It's probably the same in the USA in that who you support is hereditary and you are born into who you support.
Newcastle supporters are more active in protesting, they absolutely hate their current owner (Mike Ashley) and there are weekly protests against him and his other business interests.
The majority of rivalry between Sunderland and a Newcastle supporters is good natured, where I work it's a 50-50 split on who supports who therefore there is some good banter especially when we play each other.
I hope this is useful, let me know if you want to know anything else.
