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.
Bad blood? No man, there is no such thing between Vinicius Junior and Mbappe.

Haven't you seen Vinicius' assist to Mbappe in their last La Liga game? If there had been a problem then I'm pretty sure Vinicius would have used the ball himself there.
Anyways, the only problem has been said to be the balance of salaries. They say he asked for an equal amount of salary to Mbappe's. But the team didn't want to meet that demand. I hope they work it out in time to prevent a potential unrest.
