I've managed to get a lot of those released during my time as a fan, though a few have proved elusive and I'll continue to try track them down.
My personal favourite is the 1997-1999 home shirt by Kappa, even if it divides opinion amongst fans due to the shade of blue.
The most recent offering from Umbro is also very nice, and in line with the high standards they set when coming on board back in 2009.
The worst shirt is probably the silver effort from 2000-2002, especially when you consider it was worn with neon yellow socks.
