MUNICH -- Seventeen-year-old Lennart Karl was handed his first Champions League start and made the most of it.
Within five minutes of kickoff against Club Brugge on Wednesday, Karl became Bayern Munich's youngest Champions League goalscorer in style, breaking a record set by Jamal Musiala.

Karl's contribution was so explosive that it left Bayern coach Vincent Kompany concerned about the effect of all the attention on his young winger.
"I'm not a fan of hype, and now he will be getting some of that. I'm a fan of training and calm," Kompany told broadcaster DAZN.
"His performance today was good. Everyone knows he can score goals and if he keeps going like this, he'll get a chance and maybe at the right time he'll need a bit of calm."
Karl picked up a pass in midfield from Jonathan Tah, dodged past defender Brandon Mechele and surged to the edge of the Brugge box before hitting a swerving left-foot shot which went in over goalkeeper Nordin Jackers.
Karl sprinted to the corner to celebrate with a knee slide before Bayern striker Harry Kane and midfielder Aleksandar Pavlovic rushed over to hug their young teammate.
Karl's goal set Bayern on course for a 4-0 win featuring two other landmark goals. Kane scored his 20th of the season in all competitions with a tap-in off a Konrad Laimer cross, before Luis Díaz scored in the Champions League for Bayern for the first time since signing from Liverpool. Nicolas Jackson made it 4-0 on a rebound in the 79th minute.B
Bayern become one of five teams in the league stage to win all three of its games so far.
At 17 years, 242 days old, Karl breaks a record set by Musiala, who was 121 days older when he scored against Lazio in a round-of-16 game four years ago.
Karl wears the same shirt number, 42, that Musiala wore in that game.
It's Karl's first senior club goal in his 10th Bayern appearance in all competitions. He made his debut at the Club World Cup in a 10-0 thrashing of Auckland City in June.
