The fact that every gangway was full of fans in the top half of the stand and rows had more fans than seats suggests people didn't use their own seats, besides Fulham has an electronic system for ticket entry so I guess it wouldn't be too difficult if they were willing to share the data
What like most away games this season
Edit: by the way there are still 91 tickets available for Leicester and these have been available to everybody with a purchase history for over a month
