My favourite game will always be my first live derby game, 3-0 against arsenal, Wanchope double and Sturridge. Ian Wright missed a penalty with Poooooooom in goal.
My arsenal supporting brother sat in the home fans whilst asrsenal lost their first game of the season (I think). Not an important game but reminds me of the high point of supporting debry, time with my dad and brother and some of my favourite derby players ever.
