Yep. It's the elephant in the room (no, not Higuain) that no one seems to want to address. Reminds me a bit of Morata's second season with us. The injury hasn't helped of course, but he has struggled, especially against teams who close up shop.
Look at Higuain start the counter and then sprint the whole field to score. He must have been the first kid inside for dinner when mom called everyone in from the street.
