Alcorcon consider themselves champions (of Real Madrid)

Although they lost the away leg of their Copa del Rey fixture against Real Madrid 1-0, third division Alcorcon still completed their shock 4-1 aggregate upset over Spain's most expensive team and advanced to the fifth round (of eight) in the tournament.

For Alcorcon, this was their championship, though, and without a doubt the club's defining moment (it was only founded in 1971).
