Scotland
Celtic-Aberdeen
Former Liverpool manager Brendan Rodgers has lead Celtic to domestic glory once again, winning the League Cup and Scottish Premiership, in an incredible unbeaten streak.
On the other hand, the 'Dons' came second in the league and have gone 27 years without lifting the Cup.
England
Arsenal-Chelsea
With robust security measures taken in and around Wembley, the 136th FA Cup final will go ahead with Wenger in the spotlight.
Having not qualified for the Champions League for the first time in 20 years, the French manager could lift his record-breaking seventh FA Cup trophy or, in case of a defeat, fuel the protests asking for his exit.
If Chelsea win, Antonio Conte would become the second Chelsea coach to achieve the 'double' after Ancelotti did so in 2010.
Serbia
Partizan-Red Star
Not only a Cup final, but a Belgrade derby to end the season. A heated contest, usually prompting serious incidents from supporters of either side.
Germany
Eintracht-Borussia Dortmund
A German Cup final and no Bayern Munich? Dortmund stopped Ancelotti's team in their tracks in the semi-finals, and are now the big favourites in the final in Berlin.
Thomas Tuchel has the chance to win his first title, against the first German team to play a European Cup final (1960).
France
Angers-PSG
Winners of the Super Cup and the League Cup, PSG will look for a third trophy of the season after damaging defeats in the Champions League and the Ligue 1.
Angers have made it to the second final in the history of the club, so Unai Emery's team are expected to win.
Spain
Barcelona-Alaves
Barcelona want to bid farewell to coach Luis Enrique in his last match for the club, by winning a final title.
Alaves have never made it to the Copa del Rey final before, but they have shown they know how to face top teams.
It will be the last official game ever to be played at the Vicente Calderon before it is torn down.
Portugal
Benfica-Vitoria
Benfica lifted the league title and they will look to do the same by winning their 26th Cup against fourth-placed Vitoria.
The VAR will be introduced to Portuguese football for the first time in this match.
