IIRC, it was announced on Granada's Friday night preview programme 'Kick-Off' on 5 January and was discussed with great excitement. The next day was FA Cup third-round day but we had a day off as we were due to play the winners of the second-round tie between Barnsley and Rotherham. That one had gone to a second replay, which hadn't taken place yet owing to postponements and the packed festive fixture list.
(I only discovered this recently, when I read an account by Kevin Cummins of how he was able to stage his iconic photoshoot of Joy Division in the snow in Hulme on the Saturday when the band would ordinarily have been at Maine Road. I always assumed the snow in Manchester meant our home game was off, but I looked it up and Kevin was spot on.)
So Mal's first game was the following Saturday at Leeds. We drew 1-1 thanks to a pile driver from sub Brian Kidd, who was on playing in the centre of defence in place of the injured Watson. It's a cracking goal and is on YouTube for anyone who can be bothered to look it out.
We then played the home Cup match against Rotherham just over 48 hours later, the goalless draw being pretty dire as far as I recall. The replay took place 48 hours after that and we won, but threw away the home game on Saturday against Chelsea to lose two points we should have taken easily. They went down that season and were absolutely shite, but maybe it being the fourth game in a week caught up with us.
It wasn't exactly an auspicious start for Mal, though, and I remember my dad saying that, without Mercer to guide him, Allison wouldn't produce anything good. I wish we could look back and laugh about how wrong he got it, but regrettably it was pretty much spot on.
