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.
