THIS.
The definative post on this whole thread, plus TLO's design of course.
No-one is suggesting the whole crowd waving Argentine flags, just one flag/banner hanging from the back wall.
The Large One's design for me.
The Argentine flag, and Leo in his Albion Kit....that means something to everyone, the regional flag would mean nothing to 90% of the home fans or the opposition.
We are happy to cheer his goals and chant his name, then we should embrace his nationality.
