Dybala VS. Mbappe ?

lol will never happen. Mbappe is much more than a talented player.
He's young, the best French and even world prospect and he's from Paris' suburbs.
He's also a huge marketing project, even more than Neymar. They bought him for 180 million, he's worth twice as much for PSG now... and I'm not exaggerating.
Plus Dybala wouldn't fit in Tuchel's system.
Paris won't want to sell Mbappe before a long time and Mbappe will want to stay as long as he thinks he has a chance of winning the Champions' League with this team.
