No. But there is certainly a trend for Brazilians to lose motivation. For that reason id put Ronaldinho ahead of him. A truly great player that completely lost interest. Should have been regarded as one of the greatest, possibly still is, but not as great as he could have been.
I heard recently Neymar doesnt like football. His father pushed him into it.
Think Ronaldinho achieved more than Neymar has. He was football's poster boy and adored by millions around the world as the epitome of joga bonito. No such love for Neymar. As I say, the worst best player.
