I could see this happening months ago. And I knew Hart would get the number one with the way pre season went. While it's disappointing if we lose Shay, we have to remember he is in his mid 30s now. Every season could realistically be his last so I wouldn't want to wait on the bench either. The "stay and fight for your place" talk is less applicable to keepers as it's rare for them to get injured and it's detrimental to rotate them.
So yeah, disappointed with Shay but understand his decision at the same time. Nobody has two top keepers on their books.
