Actually, despite I had them set as a possession team Benfica attempted several time long balls to their attackers. I didn't see them passing more the ball at the back.
So yeah, it could suit Long ball teams such as Sunderland or Burnley.
Of course it needs more testing.
I am streaming, testing Monaco with G/O, if you want to join:

Edit:
Really liked what I have seen from Monaco on G/O. It suits well their style of play with a high press but not necessarily sending a high numbers of players forward.
