All about taking your chances, innit.
Sessegnon and Mitrovic didn't. Liverpool's lot did.
In any case, the result against Liverpool was as a direct result of The Arsenal playing that dreadful Mariah Carey Christmas song at half-time versus Burnley.
There are Christmas songs, which are all shít, and then Mariah takes that particular one to the next level of shítness.
Karma what done it.
