Which is the only non-English team to win the FA Cup?

The 1927 FA Cup Final was an association football match between Cardiff City and Arsenal on 23 April 1927 at the original Wembley Stadium (then called Empire Stadium). The showpiece match of English football's primary cup competition, the Football Association Challenge Cup (better known as the FA Cup), it was the first such final to be broadcast on the radio. The victory by Cardiff marked the only occasion in the history of the tournament that the trophy had been won by a team outside England; the Cup had previously been referred to in the press as the "English Cup".

The only goal of the game was credited to Hughie Ferguson after the ball slipped out of the hands of goalkeeper Dan Lewis, and he knocked the ball into the net with his elbow. Afterwards, he blamed his new wool jersey, saying that it was greasy. This resulted in the Arsenal tradition of washing goalkeeper jerseys before every match.
