In fact, even though waiting until Harry Kane finishes his contract in 2024, this also requires bigger funds because of course Harry Kane when he is on a free transfer will be contested by other clubs, not just Bayern Munich.
So I think for 2024 Bayern Munich must provide a good offer to be able to get Harry Kane.
If not, it is possible that Bayern Munich will not be able to get him because they will fight over Harry Kane with other big clubs.
Players like Harry Kane will always be targeted by many clubs, but I don't think that there will still be many clubs who want to go after him when he is past 30. Even though he will be on a free transfer after his contract ends with Tottenham, because at the same time young players with good achievements can also appear so that it will also create separate competition for Harry Kane. And every team will certainly pay more attention to young players who can be trained to give achievements to the team in the long term.
