Mariah Carey's All I Want For Christmas Is You vs. Wham's Last Christmas: Which Christmas classic wins?

officialcharts.com:

Choosing your favourite Christmas song is a bit like picking out a new festive jumper: they're all vaguely similar and have a very limited window of use each year - yet they're extremely, unequivocally important.

And while there are plenty of Christmas classics to enjoy, when it comes to the Official Chart there are two obvious favourites that out-twinkle the rest: Mariah Carey's All I Want For Christmas Is You, and Last Christmas by Wham!.

Famously, neither song has reached Number 1 in the UK, but chart history could at long last change this week, as both battle it out for the top spot on the Official Singles Chart.
