Vinicious being sold? That doesn't sound like it makes sense at all. I mean he is a great left winger, Ballon D'or level player, and I do not think tat they can replace him with anyone better. Or they need to just put Mbappe to left, and then go find some striker they can buy. Which they needed for a long time but they failed to get it so far.
Why not? as long as there is the right offer especially when looking at the current rumors about SPL who are even ready to give a clause that is actually quite crazy for a player then this could happen in the end.
He does have good qualities for a player but at some moments even when his name is raised as one of the Ballon D'Or candidates it seems like his ego actually looks bigger for now than his performance. We can see how he was at the CWC although his performance wasn't bad but he also wasn't very good and stood out in the end.
So when there is an offer that is indeed profitable in terms of business I think Madrid will also think about this.
On the other hand in terms of chemistry uniting Vini and Mbappe in a scheme where they have the same position is also currently less effective actually so if indeed Vini wants to leave and there is an offer that can really make Madrid for a large amount then this can still happen.
