Seeking Architect - Soccer Stadium

I just checked out every soccer level the one guy had like 60 seats but it was small cartoon level.
Maybe theres a Roman Arena that could be made into a soccer stadium.

On google the grass is in squares from light green to dark green.

Its 17 squares long, and 12 squares wide you were off by only like 3 squares I think.

Thats just for the grass total area, let an engineer calculate the full stadium, lol.
