I wouldn't say he is definitely right, although he is of course perfectly entitled to raise the issue. As a (relatively part-time) LFC fan I can tell you that the whole Hillsborough thing has resonances which, even to this day, have left the club traumatised beyond belief. Perhaps one day LFC will once again play matches on 15 April (and I expect that finally getting the police to admit to a degree of culpability will be the catalyst for this). However in the meantime, if they want to opt-out of playing on the Hillsborough anniversary, I can't see how anyone can make them, or even what they would expect to gain by doing so.
Sadly, and for all that Alan Davies has made a valid point, the awful, snide manner in which he chooses to do so rather detracts from his argument. I have always liked him (QI and Jonathan Creek being among my favourite programmes of recent years), but I feel rather let down by his childish rant.
Here's my question: in an era in which we are (sadly) all too accustomed to games being shunted around to suit the vagaries of TV scheduling, why couldn't BOTH matches be played on the 14th…? Play the Merseyside derby at a neutral venue in the NW (Old Trafford, say) with an early kick-off, and then play the Chelsea-Spurs tie at tea-time at Wembley. Simples.
