Number 2 ... quite literallyThis is either of 2 cases:
1. Ref totally forgetting about a new law (it won't be the first time this has happened in EPL).
2. Ref knowing it is against the law but still doing it because they think it's best (it won't be the first time this has happened in EPL).
I suspect it case 1 here.
And someone was saying these refs care about their score
By now, even the average County Ref would know you can't have a contested dropped ball
