It's easy to calculate Bruno Fernandes’s worth to Manchester United. Easier still to see why individuals at a club so preoccupied with financial turnover would make such a spectacular balls-up in their choice of which numbers to value.
His claim that the club were open to selling him in the summer ('United wanted me to leave, I have that in my head. I think they didn't have the courage because Ruben Amorim wanted me here, but from the club's side I felt that, if I left, it wouldn't be so bad') is no great surprise on two fronts.
