The 1999–2000 UEFA Cup season was the 29th edition of the UEFA Cup competition. The final took place at Parken Stadium in Copenhagen and was won by Galatasaray, who defeated Arsenal in the final. The game was scoreless through the first ninety minutes and stayed that way through thirty minutes of extra time. The match went on to penalty kicks in which Gheorghe Popescu scored the winning goal to win the cup. Galatasaray won the cup without losing a single game. The competition was marred by violence involving Turkish and English hooligans in the semi-finals and the final, in particular the fatal stabbings of Leeds United fans Kevin Speight and Christopher Loftus by Galatasaray fans in Istanbul.
