I think there's bad blood between the two, if we go into the Vini and Mbappe topic.
i am no expert, but i see that both have a tough and prickly character and therefore it is difficult for them to meet halfway.
Between the two, the one i don't like is Mbappe.
Where do you get such informations?! Are they even valid, do you have anyone from/in the dressing room leaking information to you?! If you don't then, these assumptions makes zero sense for real. There's nothing going down between these players. I have only seen rumours of Vinicius Jr wanting his salary toped as Kylian Mbappe, asides that, nothing. I have always said it before now, people who hate Kylian Mbappe needs fixing.
