I always tend to feel a bit alienated at these games, don't enjoy them to be honest. I have literally never knowingly interacted with a Forest or Derby fan in my life so have never had any real added emotions during these games, I didn't even realise they were consider rivals until I was about 11 and played Championship Manager for the first time where they were listed as our rivals. Always been brought up on, and still only hear people round me refer to Cov when talking about hatred and making the obligitary incest jokes.
Sure I'm probably the only one, but Derby and Forest games tend to be my least favourite of the season.
