(just) as I expected
As I anticipated or suspected. The phrase is often said with a note of annoyance or frustration. My mother stole all the attention at my birthday party, just as I expected. As I expected, I didn't get the promotion. The boss just doesn't like me.
(just) as I expected
I thought so; I knew it would be this way. Just as I expected. The window was left open and it rained in. As I expected, he left work early again.
