Reading fan here. I could name a few I 'hate' but you wouldn't have heard of them. Love - sir Steve coppell and the 106ers, obviously, but we've also had some great players over the years, Jimmy Quinn, Phil Parkinson, Trevor senior, robin Friday, shaka hislop.
Actually - hate is probably the current board. They came in promising money, didnt back it enough to stay in the premier, once that cash flow dried up decided it cost more to run a FC than they'd realised, and are now trying to sell out to 'another' middle east consortium if the rumours are true.
I keep trying to hate Swansea, because they took our manager (ok, we sacked him which was a rubbish decision, certainly in hindsight) who then did at Swansea exactly what he was trying to do with us. And then to rub it in, stuffed us in the playoffs and took them up when it should have been us. And they had better songs and singers at Wembley, bloodywelsh!!! But they're too good to hate properly.
