Feyenoord, Parma, Eintracht Frankfurt, Borussia Mönchengladbach, FC Porto and IFK Göteborg have won the UEL twice.
English sides Tottenham and Chelsea and defending UCL Champions Real Madrid have also lifted the UEFA Europa League trophy two times only.
Juventus
Another Italian side, Juventus also holds three UEFA Europa League titles. The Old Lady got to touch the Silverware in 1976/77, 1989/90 and 1992/93. And it's fair to say that under Massimiliano Allegri, the Old Lady is far from its Glory days.
Inter Milan
Inter Milan has also lifted the prestigious European prize three times. But Nerazzurri's all title triumphs came in the 20th century, not in the modern era. Inter won the title in 1990/91, 1993/94, and 1997/98.
Liverpool FC
The only English side with three UEFA Europa League titles is Liverpool FC. Their most recent title came in 2000/01 when the Reds won by a Golden Goal against Alaves. Moreover, their other two title wins came in 1972/73 and 1975/76.
Atletico Madrid
Another Spanish club, Atletico Madrid is just behind them with three UEFA Europa League titles. Atletico's first title came in 2009/10. Afterwards, they defeated Athletic Club in 2011/12 and Marseille in 2017/18.
Sevilla
The most successful club in the Europa League is Spanish side Sevilla. They have lifted the UEFA Europa League title on six occasions. Sevilla won their first UEL title in 2005/06 against Middlesbrough. They clinched the title in 2006/07, 2013/14, 2014/15, 2015/16 and 2019/20.
