Shortly after lighting up the European Championship, two of the world's most exciting young players shone on club soccer's biggest stage.
With mixed fortunes, however.
Teenager Lamine Yamal's goal couldn't prevent 10-man Barcelona from falling to a 2-1 defeat at Monaco on Thursday in the Champions League — ending the Spanish club's perfect start to the season.
Meanwhile, it took Florian Wirtz less than five minutes to score his first Champions League goal on his debut in Europe's elite club competition.
Wirtz also netted another as Bayer Leverkusen romped to a 4-0 win at Feyenoord.
''I was really looking forward to this game for the last few days already, and that's how I approached the game too. I think, however, it was like that for everyone," Wirtz said.
"I didn't count on finishing with two goals, but I had two chances and I just used them both. And then you can just build on that and I can just try to take my chances in every game.''
Leverkusen lost in the Europa League final in May, its only defeat in a remarkable season that saw it win the Bundesliga and German Cup.
