Yeah he really is imo. He bogs down our attacking play like no other. Him and Khedira that is. Higgy is standing still way too often when we attack, never gets on the end of anything we put into the box. Defenders easily get in front of him to intercept balls even from disadvantaged positions. His passing is poor, his shot takes him forever to get off so its easily blocked, his pace is gone so he's outrun all the time. The guy is in awful shape and awful form this year.
So yes, when 90 million went to purchasing him, he is our biggest problem right now, both figuratively and literally.
