I was fortunate enough to get to all our 4 recent games at the new Wembley. On each occasion, fans of both teams cross paths and mingle all around the outside perimeter, both before and especially on the way out.
I’ve often wondered what would happen if 2 teams whose fans absolutely detest each other were to play a play off final there.
If we played Bristol City, or Swansea ( which almost happened a few seasons ago), I could foresee carnage on the way out after defeat for one of them.
