But in this particular case it doesn't really matter what anyone else did.
A defender can't cut out every single cross. He struggles big time against Maeda as he's rapid. Crosses are going to come into the box. In every game of football, both teams get several crosses in per game. What you don't see in many games of football is what Lundstrum then did. It's 100% on him that particular goal.
Most goals you can say x has lost his man, y should have tucked and z should have shown him the line or whatever. But that particular goal is blatantly the fault of one man and anyone trying to say anything else is off their head.
To be clear, if O'Reilly steps onto that cut back and scores or even if Lundstrum is under pressure and bumdles it in trying to clear it, Tav is largely responsible for the goal. But, in the circumstances it went in, its essentially completely irrelevant what anyone else but Lundstram did. It's an incredible own goal.
