Lol, that's how it is when a player is labeled "star", whatever happens to them is always a rumor in the end. Even when he's out of sight, there will still be rumors, and the rumors will be diverse, and probably never thought of before.
Even the emojis he posts will become speculation, just like now. Lol
But I'm just like you, that I'm just waiting for official news, because I've been through so many rumors about her, and it's just a rumor, no official news, no confirmation that eventually sinks in.
I understand that Mbappé is a big star. And anything he does. He's definitely going to be starting some speculation about him, especially when he is not certain about his future. I also understand that the media is also going to try to take advantage of that, and make news out of almost nothing.
But what I am trying to say is, is there actually any reason to make anything out of the emoji that he put on his post? I definitely do not think so. He is definitely a big star but the media is just trying to print news out of thin Air. And right now I am actually angry about this because most of the News does not have any base. I mean why are they talking about him going to another club? Just because him giving some emojis on his post?
Your question has been answered, how the media seize the moment to make speculation and give useless baseless rumors as you said. That's what always happens when a "star" player does something including making a post. And this is not the first time this has happened, even before it happened to other players.
And it's back to us to filter every news or rumor that comes. Therefore, I personally do not want to speculate too much in response to existing rumors, especially for rumors that have no basis that can really make us speculate like that.
