He is definitely the second best player in the world right now.At last CR7 loses that spot.
As for the Messi vs Ney thing,i have to say 2+1 things:
1)Messi is considered the GOAT because he has been in insane form for like 8 years now.If Ney will ever surpass him,he first needs to reach that level(which as some people said is not THAT far from his level),but most importantly he needs to keep it up for years.
2)I think most people,including me,get into this type of discussions because Messi is injured.When he will come back we will all remember who is the GOAT
Bonus)That said,Ney is brilliant!
