Correct. Amateurs ball watch, professionals if they do get rightfully kicked up the arse. 30 minutes he went on far, no excuses to not bust your arse, it's a basic requirement. We would all be sitting here happy with him if he did that in spite of him not being good enough.It’s not his fault no.
But imagine say Rodri or even Fernandinho in that situation. They get back in to cut off the simple pass to Hwang after it pinballs a bit.
His positioning gave their forwards both time and space to stroke a square ball and finish in the opposition box.
It’s schoolboy stuff for a DM!
