Schards#2 OUT for any friendly against any team unless the cost is minimal and I have absolutely nothing else to do.
I would not pay £20+ for any friendly involving any two teams on the planet
What about a World War II style Allies XI vs Axis Powers XI, played in Escape to Victory kits, and your seat was right up near the commentary box sat above a wall of Nazis in uniform?
That'd be worth twenty quid easily
Or if a full-strength Argentina took on Brazil at the Madejski? You wouldn't pay for that?
