It's not new, in the eyes of some fans he is known as an ambitious player to score goals alone, especially since his name became known after join with Paris Saint-Germain. That's also what makes some fans dislike him because he's greedy
But it's natural for me, because Kylian Mbappe is a relatively young player, for his future career glory, Mbappe needs achievements and top scorer is his goal at the moment.
So I wouldn't be surprised if he has a record no assists for another PSG striker
But indeed for fairness this can indeed be considered natural, he is one of the young players and indeed his performance is very good so when he is given more proportions at the club it will certainly be like that so it is difficult to change his attitude now.
There's no way to justify Mbappe's act if it is true that he doesn't assist his team mates. Mbappe is not the only good player in PSG, before Mbappe started scoring Messi was scoring, Neymar was scoring it doesn't mean he is the only one that can put the ball at the back of the net.
Even if Messi overlooks his behaviour, Neymar will not overlook it and even if both Neymar and Messi do, the fans shouldn't keep quiet, it does promote healthy and team football.
