Is it at Norwich though? there is a lot of Brighton badges adorned everywhere. Looks more like Lancing to me. Maybe it's the Amex and we are celebrating keeping the score below 3 v United.
That’s not Lancing and the badges are on the team equipment the club takes to away matches. Presumably Norwich have allocated a different area as an away changing room than usual in an effort to do some sort of social distancing. Maybe the normal dressing room is tiny are it’s a really narrow corridor outside?
*Edit* then I see the other posts saying it is a temporary dressing room!
