Hi there :)

just that you added the name of the stadium to the pitch itself without giving a proper reason.

I'd like to ask why you did that since the name is already tagged to the statdium multipolygon itself. 

Also, I'd very much like you to please add proper comments to your changes since your double digit numbers don't really help anyone.
