Would be a nice touch to be able to choose the amount full that your stadium is for home matches, even in ultimate team.
Division 10 matches shouldn't be played in front of 70,000 full capacity stadiums, but could have just 20,000 with rows of empty seats or a sparser crowd.
Would impact on crowd atmosphere in the stadium and be more psychological.
Could even replace some empty seats with banners or flags for added authenticity.
Replicate the behind closed doors experience when you want to.
