1-It was a mistake nevertheless,and if he was disoriented he should have made it known and don't play with it,no execuses for this one.
2-Did he really touch the ball? The streaming wasn't on high quality but I felt he really didn't touch the ball. surely not a mistake by him anyway

To criticize him after a match like this you have to be pretty delusional.
