For those wondering the record PL score is 9-0 (by United as it happens). So they need more than double that. The highest ever in the first division is 12 - 0 twice - the last time 107 years ago. The highest in the four English divisions is 13-0 achieved first by Stockport County in Div 3 in 1934 and twice since by other teams(with the last time 70 years ago). So you can see how extraordinarily unlikely (and fishy) this would be.
