Harry Kane is considered to be operating in the shadow of Bayern Munich wonderkid Lennart Karl, with the 17-year-old sensation being likened to Lionel Messi. He is, having made a stunning senior breakthrough at the reigning Bundesliga champions, also being challenged by Dietmar Hamann to match the levels of Portuguese superstar Cristiano Ronaldo.Exciting prospect Karl made his bow for Bayern at the 2025 Club World Cup, with the youngster first figuring in a 10-0 mauling of Auckland City. He continued to star in pre-season and recorded his first competitive goal in a Champions League clash with Club Brugge - becoming the youngest player to net for Bayern in elite European competition, as that record was snatched from Jamal Musiala.Three days after that effort, Karl was on target in a Bundesliga meeting with Borussia Monchengladbach. He has also become the youngest player to record a goal and assist for Bayern in the same game.Another entry in the history books has been snatched from Real Madrid’s former Paris Saint-Germain forward Kylian Mbappe, with Karl the youngest player to score in three successive Champions League matches,He is causing quite a stir, with ex-Bayern midfielder Hamann telling JeffBet: “Lennart Karl was asked who his idol was, and he said Lionel Messi. I don't think there's any surprise there. Messi dominated world football for the last 15 years with his low centre of gravity and the way he dribbles. Karl dribbles in a very similar way, there are many other similarities when you watch him play.“Karl has played around 20 games for Bayern and been fantastic, but you don't want to compare him to someone who has dominated football for 15 years. They do play in a very similar way, though.“He's taking all the headlines in Germany at the moment and carrying the attack. People are saying Kane is in Karl's shadow at the moment. Look at the game against Arsenal, Karl was the one who scored and was the most efficient player going forward. He's undroppable at the moment. If there was a Champions League semi-final or final tomorrow, Karl plays, Jamal Musiala, will need to work his way back into the team. The positive is that Musiala doesn't have to rush back from his injury. He'll have to do very well to replace Karl.”Looking for smarter football bets?
