Blues have already had the pleasure of the Banbury-based official refereeing one of their games this season whilst Mr Gallagher has also refereed just the one West Ham fixture during this campaign.
The last Blues game that Dermot Gallagher took charge of was in our 1-1 draw against Portsmouth on 17th September 2005 when Nicky Butt was shown a red card.
The last time Dermot Gallagher took charge of a West Ham game was in their 0-0 away draw at Newcastle United on 20th August 2005. Marlon Harewood picked up a yellow card on that occasion.
