How do you solve a problem like Zlatan? Since the big Swede hit his stride in late May, nobody has figured it out. Zlatan Ibrahimovic, quite possibly the best goalscorer not named Messi or Ronaldo over the past decade and change, is scoring about once an hour since June began, and the Galaxy are averaging two points per game since that point. Having sat out last weekend’s wild come-from-behind Pontius Special in New England, Ibra is likely to show up in Philly this weekend rested and ready to roll against two teenaged center backs. Not that it matters who the Union put on the pitch to defend him; if there’s one constant in Ibra’s career, it is that he cares little for anyone but himself.
