If thats the way they like to party? So be it!

I hoped Harry Kane would come to Real Madrid :(

And to answer your question, I don't think it's slavery at all. It's sports business model. And players have free will to do what they want.

Business, I think...

I’ve often wondered how professional athletes process all of that.

I think it's a different thing, like buying the rights to his services as opposed to buying a person, presumably he agreed to the terms of a contract with the British club and the German one simply bought that contract... In becoming self-employed I have found it to be best practice to have language in a contract covering changes like this, specifically that either side can rip up the contract in the event of a covered change. Hopefully this player has that language and he'd be free to renegotiate.

It just sounds like slavery because of the use of the terminology "buying" a person, but, like Ed said, it's simply a switch in employment. The player isn't being forced to work, and he's being paid a lot of money to do so. He can retire if he wishes.

Harry Kane, he is free to reject the contract offered by Bayern Munich, and see out the remainder of his contract with Tottenham Hotspur. He cqn leave for free next year, when his contract expires, and will be able to negotiate a contract with other clubs from January 2024. If the transfer is agreed Harry Kane will be earning some hefty inducements as well as wages and depending on his current contract, a share of the transfer fee.

It's business. The club needs to maintain its caliber (and revenue) and the players are extremely valued as a result.
