The way Neymar got injured was so hard when he was playing for Brazil. Neymar was injured when he was playing for PSG and he was not in good form at all. but after he recovered he just injured just again after that. That's why Neymar is very far from his good form and even if he comes back and starts playing for his team still there is no guarantee that Neymar to have a good performance as he had before because he was out on the field for a long time and this definitely affected this player. Maybe even Brazil should not count on Neymar for the 2026 World Cup anymore.
But everything changed after Neymar became part of PSG, he suffered series of injuries and from there Neymar went to Saudi with Al Hilal but the previous injury he got when he was still a PSG player made him get injured more often.
We can see again how Neymar previously suffered very serious injury while defending Brazil in the Uruguay vs Brazil match in the 2026 World Cup Qualifiers and this is where he had to be absent for quite long time.
But for the 2026 World Cup, I quite sure that Brazil will be able to have good performance. Moreover, I also sure that Neymar will be able to participate in defending Brazil in this most prestigious big competition.
