Aye, even looking past the whole Pardew thing I've never been a one to decorate overly with football stuff. Just looks shit imo.
If I had my own house with a spare room I would have some NUFC pictures and stuff, though nothing tacky.
It's possible to create a tasteful, non-wanker man-cave. Some NUFC memorabilia, lush carpeting, a big comfy chair and a mini-fridge. That's the dream.
