Lennart Karl reveals secret of his success at Bayern and Germany

Against the Finns he swung in a quick corner for Deniz Undav to open the scoring in the 34th minute, then delivered another assist to the Stuttgart striker in the 57th. Germany manager Julian Nagelsmann praised him: "He's a player who can operate in several positions and will be very valuable to us."

In Sunday's match in Mainz the 18-year-old started on the right wing, forming an incisive front three with Bayern Munich team-mate Jamal Musiala and Liverpool's Florian Wirtz. Captain Joshua Kimmich said: "At that age you have a carefree attitude. He should savour this phase, go out and enjoy himself." He added: "He needs to believe in himself, take the ball, take risks and have a go at goal."

Karl, who has now made two senior appearances as a substitute, admitted he felt "goosebumps during the warm-up" and added that the national anthem and "my assist were special for me. I was really pleased and I'm happy about the trust the coaching staff have placed in me."
