Well fortunately, as of today they have both managed us for 17 games this season:
Neil Warnock: Played 17 Won 5 Drawn 7 Lost 5 Scored 25 Conceded 25 GD 0 Pts 22
Neil Harris: Played 17 Won 7 Drawn 7 Lost 3 Scored 23 Conceded 22 GD +1 Pts 28
Harris has the better record and yet it was Warnock who had the entire summer to sign and train players.
