Giant Killers Maidstone.

I think, Maidstone players are semi-professionals. at least.

But something like that can happen in the cup matches elsewhere, too.
In Germany, in 2020, FC Saarbrücken (then 'Regional League Southwest', fourth tier, 5 leagues in Germany below the professional 3rd Bundesliga) reached the semi-finals.
And in 2001, Union Berlin (then Regional League North) even reached the final.

I know what you're saying re Maidstone, (and Ipswich), neither are at the opposite ends of the leagues.

I wasn't speaking specifically of these two sides, who are not Roy of the Rovers storymakers, but the competition in general.

Obviously Scholing United beating Liverpool would be a far bigger killing but that's not likely to happen, and the Maidstone result is as good as it gets.

And thank you for educating me about other the German competitions.

Our pundits like to tell us of the uniqueness of the FA Cup and I was falling for the hype.

It's still a good result.

Saints managed a last minute equaliser against Watford for a replay.

The winner will face Liverpool.
