Let's make it a test for a change.
Your team is losing a match, again. You can express your anxiety saying
"Неужели мы опять проиграем?"
And you may say about your team performance
"Разве это игра? Это позорище!"
or
"Разве ЭТО они называют игрой? Это позорище!"

Good example

PS. In the last sentence, you can also use Неужели, methink...
