Neither Huddersfield or Birmingham are going well in this division. The terriers are experiencing difficulty in the step up in class from league 1 whilst Birmingham are in the midst of financial meltdown due to corrupt overseas owner, debts and the threat of administration.
I predict a forgettable game here played out in the backdrop of two under confident teams. The hosts may be the slight favourites however they have no league wins in the last 10 games dating back to 10th November, they also have three consecutive home draws against teams in a similiar place to themselves being Sheff Wed, Blackpool and Bolton.
Birmingham have slightly better form although still only 1 win in 6 league games and they have 4 away draws against mid ranked opponents like Blackpool, Blackburn and Notts Forrest.
I think this is score draw.
