MLS still plays games during FIFA's international windows, when national teams summon dozens of the domestic league's stars away from their clubs. Ideally, this contest would feature Toronto's Jozy Altidore and Michael Bradley against RSL's Kyle Beckerman and Nick Rimando. But of those four marquee Americans, only Beckerman remained home. The rest are in Europe with Jurgen Klinsmann and the U.S. team. At least Toronto will still have Italian playmaker Sebastian Giovinco. His duel with Beckerman should be fun to watch.
