Luzern win Swiss Cup
The Luminaries, who finished fifth in the Swiss Super League, qualify for next season's Europa Conference League second qualifying round.
Luzern captain Christian Schwegler lifted the trophy in what was the 36-year-old defender's last match before retirement.
The match was played behind closed doors at the Wankdorf Stadium due to coronavirus restrictions.
In the league, the ever-dominant Young Boys sealed a fourth consecutive title in April with seven matches remaining.
The Bern side will compete in next season's Champions League second qualifying round.
