You can't have Caceres on the right flank all alone. You just can't. He is a CB and should be used as such.
Now, Melo has done OK, but he needs to be more imposing with the ball. Needs to want it in midfield and control the game.
What we really need is someone like DP who can create for himself up top, because Nazio is doing a great job shutting down everything in attack, even though we got some chances.
The D just blows. That's to be expected.
