One country will provide all four finalists in the major European competitions for the first time in history.
Chelsea and Arsenal will meet in the Europa League finale in Baku on May 29 before Tottenham and Liverpool do battle in Madrid for the Champions League four days later.
Having missed out on a top four spot domestically, the Gunners can secure a place in next season's Champions League by coming out on top - something Chelsea have already achieved via their finishing position in the top-flight. That adds another layer to what is already a fascinating contest.
