The Stevenage Road stand at Fulham is listed, so they are forced to look after it, and they've done a good job. the old stand at Selhurst has had so many additions that it's hard to see what's original and what isn't.
Fratton Park. Not even close.
While some old grounds, especially those with Leitch stands, such as Fulham and Everton, have character, others are just plain creaky and inconvenient.
From my selfish pov as a memeber of the media, Selhurst has the worst facilities in the current Premier League...
