Munir El Haddadi's second-half goal was enough to see Barcelona through their UEFA Youth League semi-final against Schalke in Nyon on Friday to join Benfica in Monday's final.
El Haddadi's ninth goal of the campaign, per UEFA.com, secured Barca a vital 1-0 win at the Stade Colovray and swung a game that looked as though it might be heading for penalties.
A frantic opening few minutes with chances for both sides settled into a relative stalemate with neither side really looking able to break the deadlock until the decisive goal arrived, shown below, in the 72nd minute.
Both sides had made relatively simple work of their English opponents to make it into the last four of the competition.
Barcelona came out 4-2 winners in a see-saw contest with Arsenal at home, while Schalke had a solid 3-1 win away to Chelsea.
UEFA's Simon Hart offered a view of packed stands for the game after Benfica had convincingly seen off Real Madrid 4-0 on the same pitch earlier in the day:
While neither goalkeeper was properly tested early in the game, there were several opportunities from either side in the first ten minutes.
Adama Traore was at the centre of everything creatively for Barcelona, setting up a couple of chances from the right that were not latched onto.
Meanwhile, Felix Platte's directness nearly resulted in an early goal for Schalke, but Jose Aurelio Suarez held well from Leroy Sane's cross.
The first genuine save came from Schalke's Timon Wellenreuther after half an hour when he palmed behind Enguene's deflected shot.
Barcelona started off better in the second half, but still there was little between the two sides. With no extra time at this level, penalties were looming.
But on 70 minutes, Mohamed El Ouriachi was brought on. Two minutes later, he darted down the left flank and pulled it back to the penalty spot for El Haddadi to stroke home.
It was enough for the win as Barcelona played out the game in attack with Schalke never really threatening to equalise.
It was a solid display from the Catalans, and football journalist Rafael Hernandez was certainly impressed:
Hart also felt that the right team had made the final:
Benfica won in the most style today with their 4-0 drubbing of Real Madrid, but they were helped out by three penalties and a sending off.
Barcelona were solid and never really looked under threat while creating well. It should be a terrific spectacle on Monday when the two sides meet for the final.
