Watch: Black cat strolls across the pitch at Anfield

A black cat is never a welcome sight when you're hoping for a little bit of luck, but we're not quite sure which team is set for a touch of bad fortune at Anfield.

As Liverpool prepared to take on Manchester United in this rivalry match, one black-furred feline fan decided to get a closer look in training and, while friendly, the cat's presence might not go down so well with the losing team after 90 minutes.

It's not the first time something like this has happened, though.
