Barça winner Eintracht Frankfurt suffered a mood dampener after the gala at Camp Nou.
The Europa League semi-finalist lost 2-0 (0-2) at 1. FC Union Berlin on Sunday with a heavily changed team and can hardly achieve an international starting place for the coming season via the Bundesliga.
In complete contrast to the Irons, who also got in the mood for the DFB Cup semi-finals at the second German Europa League semi-finalist RB Leipzig next Wednesday.
With goals from Taiwo Awoniyi (17th) and Grischa Prömel (21st) they celebrated their third win in a row and impressively underpinned their new goal of the European Cup in front of 22,012 spectators in the sold-out stadium at the Alte Försterei.
In the table, Union Berlin moved up to sixth place with 47 points, while Frankfurt slipped down to tenth place with 39 points.
Before kick-off, Union's stadium announcer complimented the Eintracht fans who had traveled with them for their performance in Barcelona.
After the kick-off, however, the Frankfurt pros quickly suffered football setbacks on the field.
Due to injury, Eintracht regular keeper Kevin Trapp had to pass.
The 31-year-old suffered a sprained ligament in his wrist in Barcelona, as has now become known.
Jens Grahl moved into the goal for Trapp, making his comeback in the Bundesliga after almost six years.
Once at 1899 Hoffenheim, he made his last appearance for TSG in the top flight on May 14, 2016 – and lost 4-1.
This time it didn't end well either.
Because Union got off to a good start, further strengthened after just two defeats in the previous 30 home games and the 4-1 win in the derby at Hertha BSC.
Genki Haraguchi missed the lead in the 12th minute when his skillful extension of the header hit the post.
Even then Grahl would have had no chance.
As with Awoniyi's low shot, after the Union striker had prevailed against two Frankfurters as quickly and robustly as possible.
It was his 13th goal of the season – a club record.
The Eintracht fans were also unable to build up their team in the Alte Försterei, a temple of atmosphere.
A dream goal from Prömel in the corner destroyed all hopes of the Hessians early on.
Grahl was again unable to do anything, but he saved Frankfurt from going even further behind when he later cleared against Rani Khedira.
With a view to the two upcoming guest appearances in the cup and in the league against RB Leipzig, the Unioners no longer maintained the pressure and urge of the first half hour even after the change of sides.
Nevertheless, they controlled what was now a relatively uneventful game, in which Awoniyi (63') had the best chance of scoring the third Union goal.
However, the guests in the Köpenick forester's house were a far cry from a football festival like that at Barcelona's Camp Nou.
