Benz is a more technical than Higuain but is less of a goaltreat. Higuain nowadays is very straightforward to be honest. Gets the ball, run to a side trying to past the defender and blast it. When he gets the ball on a counter with space, he most often than not runs into bad places and fluffs the chance.
Nowadays you better limit Higuain to shoot near the enemy area and thats it.
I think this is one of the reasons why he wasnt playing to his fullest in Juve, we didnt gave him proper service so he had to compensate with pressuring defenders and getting back into our midfield to look for the ball.
Add to that that i think he started to decline this season, and dassitmane.
