Well probably the most famous football stadium for weird horse shoe like shape stadiums with lack of space would have to be La Bombonera as many of us know. If you can some how make a stadium feel closed in, even if 1 stand is totally off balance to the other stands doesn't mean the stadium can't be kick ass. Just a matter of if MLSE ever invest or come up with something to make BMO fields North End feel more closed in then just a complete open stand.

La Bombonera legend of making the best with the space they got.
