Man Friday Every team except one will lose (only) once in the FA Cup every year so this stat is virtually meaningless.
A more interesting stat is our constant failure to progress. If you gave 1 point for reaching each additional round beyond the one you started in we would surely have the fewest number of points for any club in England.
Trivia question
Which team lost twice in the FA cup in 1999-2000?
So, they will have lost an extra time and were founded in 1883. Did Reading enter directly FA cup from forming? I think it may be a down to a couple of years here.
Bonus trivia question
Which team was knocked out of the League Cup twice the same season (1999-2000)?
(i.e. ignore the individual two-legged games, it's not that)
EDITTED for the dickheads.
