Ted in 1973 Millwall played Everton at Goodison park in the fifth round of the cup, in them days there wasn't as such away ends so the Police put Millwall fans all over the ground,things took a turn for the worse when they put two groups of around 50 in different parts of the Gwladys Street Stand where fighting broke out throughout the game resulting in around 11 Millwall fans being slashed/stabbed 2 of which were serious.
My uncle was there and at half-time when he went for a piss he had a knife pulled on him as he was asked if he was Millwall, being Irish he denied it and talked himself out of a difficult situation.
We have played them a few times since and whilst there has been a few incidents over the years nothing major has happened.
Cheers Stu as I was one then.

Luckily for your uncle he had a paddy accent otherwise sounds like he would've been stabbed.
