Hazard might have been our most talented player but clearly not our closest to Ballon d'or. Lampard is obviously the closest thing we had to win Ballon d'or while playing for us, just getting 2nd behind ronaldinho because Gerrard took votes off him . George Weah was a world footballer of the year who played for us later.
Pulisic while extremely talented will never become truly great bc of his injuries. He is just not cut out to be. Havertz is the more likely candidate,but i doubt it. He is a simple, yet effective player who will produce big number in his peak but never flash people too much.
Also who it is a team sport. individual accolates should not matter that much. If we win a few more CLs and champoinships in the next decades, I could not care less about ballon d'or.
