Certainly one of the more unique players of all time. Like Kevin Durant, he combined great physical size with terrific skill and flair that made him a legend. His personality is interesting, as a Swedish fan I loved nearly every minute of the Zlatan experience but his club career was so strange, probably because of his personality. He never stayed in one spot for long which probably hurt his reputation.
I will say this about Zlatan, if he had been born in Minnesota and not Malmö he would have changed soccer forever in the United States. He would have been the perfect marketing tool, his breathtaking skills and highlight reel goals matched only by his quotable personality. He'd make TO look like Wes Welker.
I will dispute that Zlatan made Swedish football. The Sverige team that Zlatan played for as a teenager was much, much better than the team he would star for later in his career. The great tragedy for him on the international level is that he peaked right when a mini-golden age of Swedish players where finishing their careers and instead was saddled with a team of overmatched players. All of the great players of the last decade have been mostly stuck with talented and deep national teams, except Zlatan and probably Shevechnko.
