I recommend to those sitting in the lower tier to sit as high up as possible.
I sat on row 20 I think it was and spent the whole match up and down like a yo-yo because the people on rows 1 to about 5 struggle to see the bottom end of the pitch (I imagine it will be worse with the goals in the way as well) and so constantly stand as soon as the ball goes over half way.
If I was going on my own I’d sit at the front of the top tier, but as I’m going in a group I’ve given my recommendation to them.
