Jake O'Brien got on the scoresheet but he and his Olympique Lyonnais team-mates lost 2-1 to Paris Saint-Germain in the French Cup final on Saturday.
Cork native O'Brien, who was called up to the Republic of Ireland senior squad in March but has yet to be capped, scored a header. However Lyon's Parisian opponents won out courtesy of first-half strikes from Ousmane Dembele and Fabian Ruiz to end the season with a domestic treble.
The Ligue 1 and French Super Cup champions dominated the first half at Lyon's Stade Pierre Mauroy to secure their record-extending 15th cup title and first since 2021.
Dembele put PSG ahead after 23 minutes when Nuno Mendes' cross found him unmarked in the six-yard box to coolly head home, and Ruiz doubled the advantage with a strike from a tight angle at the second attempt.
Lyon pulled one back 10 minutes into the second half thanks to O'Brien's towering header off a corner before PSG keeper Gianluigi Donnarumma produced a superb save minutes later.
PSG's all-time top scorer Kylian Mbappe failed to find the net in his final game for the club, leaving his record at 256 goals in 308 appearances over his seven-year spell.
It was a momentous evening for Ireland striker Troy Parrott who scored a 31-minute hat-trick for Excelsior Rotterdam as they thrashed ADO Den Haag in the second leg of their Eredivisie relegation play-off semi-final tie.
The Dubliner is loan at the Dutch side from Tottenham and had scored 10 goals during the season and played his part in putting his current club within a step of ensuring top flight survival.
The 22-year-old opened the scoring in the third minute with a chipped finish over the ADO goalkeeper, doubling his tally on 27 minutes with another dinked finish, before clinching his hat-trick with a penalty just after the half-hour mark to make it 3-0 on route to an eventual 7-1 victory and a 9-2 aggregate triumph which sees them advance to the two-legged play-off final against NAC Breda.
Meanwhile, after enduring the pain of losing the Europa League final in Dublin on Wednesday, Bundesliga champions Bayer Leverkusen bounced back to battled past second division Kaiserslautern 1-0 to win the German Cup and secure the club's first ever domestic double.
Leverkusen missed out on a treble after losing 3-0 to Atalanta at the Aviva Stadium in midweek in what was their first defeat of the season after a European record 51-game unbeaten run.
In Berlin's Olympic stadium that will host the Euro 2024 final in July, Xabi Alonso's team took the lead with Granit Xhaka's 20-metre missile in the 16th minute.
They controlled the pace even after they were reduced to 10 men following Odilon Kossounou's second booking a minute before halftime.
Kaiserslautern rarely threatened after the break with Leverkusen comfortably holding on to cap a memorable season with a second trophy.
