Perhaps a rivalry could develop between us and them? Personally I absolutely detest every single thing about them.
We're an established club with a wealth of history an old ground, real dedicated fans who only support us and support us with a passion. They are a fake new club who's entire supporter base is made of fair weather fans who largely also support Man United. Their ground is a flat pack in the suburbs and their entire being seems to be based around the celebrity and vanity of the class 92.
Differences are a good place to start for a rivalry and there's a fair chance we could be playing them quite a bit over the next decade.
