I don't personally think the prospect of fan violence if we were to meet Sunderland at Wembley is the biggest concern - after all, I've seen us play Chelsea there three times and never witnessed any bother - but more the transport congestion thats the bigger put-off factor as far as I'm concerned. Especially as Sunderland fans will have a 24 hour head start on us for booking coaches, trains etc.
Vivid memories of taking just under 2 hours to get out of the Wembley coach park alone after our 2015 defeat to Norwich is something I have no plans on repeating any time soon.
