i'd like to see the standard "front six" (with maybe Salam for Derschang), and then up top: One of Stevenson/Serna on the left, but a bit deeper, Brenes up top, and Koroma on the right in the "Ronaldo role," ie not a ton of defensive responsibility and breaking quickly and directly, cutting in a lot.
I think this works especially well when Brenes shades toward the right, as he's been wont to do lately
edit: or maybe Salam on the left wing? Dude might be our own Fabian Johnson
