The 2003 UEFA Cup Final was played on 21 May 2003 between Celtic of Scotland and Porto of Portugal. Porto won the match 3–2 in extra time thanks to a goal from Derlei. This was also the first game to use the silver goal rule, although it did not affect the outcome of the game as Porto scored in the second half of extra-time, thus meaning the game had to be played until the end of extra-time.[
