As of my last knowledge update in January 2022, the club that has won the most UEFA Europa League titles is Sevilla FC. Sevilla has been particularly successful in the competition in recent years. The club’s Europa League victories include:
- 2005-2006
- 2006-2007
- 2013-2014
- 2014-2015
- 2015-2016
Sevilla’s consistent success in the Europa League has established them as one of the most dominant teams in the history of the competition. Keep in mind that my information might be outdated, and you should verify with the latest sources for any developments or changes since then.
