A goalkeeper scoring remains one of the great novelties of football. Something that simply shouldn't happen and occurs so infrequently, you can't help smile.
Even better when the goal carries some significance, as was the case when Liverpool's Alisson Becker kept their hopes of Champions League qualification alive in the 95th minute at West Brom on Sunday.
Sometimes a goal scored by a keeper is a total fluke - the wind getting hold of a goal kick or a deceptive bounce that catches out their opposite number - but Alisson's was a thumping header that any centre-forward would be proud of.
