Jones was to his left, thats not his area. He starts off with the player that jumped against Pogba, Pogba moves in and leaps with him so Jones backs off back into his space.
Lindelof ball watches instead of being alert and moving.
So yes you'd be 100% completely correct, if Jones was standing where Lindelof was and vice versa. But actually Lindelof was marking the space where the goal came from. Could have been helped by his goalkeeper. He wasnt
But the ball does not really drop into «his» zone. It drops close to it. And he does get close. But do to the nature of the situation he is not able to get there quickly enough. It would be incredible defending if he did. He has his back to his own goal when Huddersfield cross the ball (naturally). Zanka has the advantage of facing the goal, and being able to move in between the lines at full speed. In these type of situations you rely on the people man-marking.
He also needs to read the situation to get an understanding about where Mouiner will head the ball. I’m not sure one should label it «ball watching. Its not on a Chris Smalling level of ball watching anyway.
He actually look towards Zanka before turning towards Mounier, but at this point he will note that Herrera is tracking him. When Mounier heads the ball Lindelof immediatly moves towards the zone where Zanka arrives, but has a disadvantage compared to Zanka who is facing the goal and at speed. This is exactly why you should not stop tracking «your» man moving in between the lines at speed.
Pogba could have done more and Herrera should have done more, but that goal is really not at Lindelof. You just look like you have a biased, unjust agenda when claiming that it was.
