AC Milan started the match off with a bang when Pato scored from the kickoff, beating Sergio Busquets and putting the ball past Victor Valdes in the 23rd second. That's officially the fastest goal in UEFA Champions League history. Barcelona still look a little shaken, but they're settling back into their usual rhythm, passing the ball through midfield and barely allowing the rossoneri a touch.
But the early lead has bolstered the visitors' confidence, and they're intent on keeping Barcelona from finding a goal. Nearly every Milan player is taking up a position behind the ball, ready to expose the home side on the counter, but also content to simply frustrate Barca.
However, playing 90 minutes of defense could go horribly wrong for Milan. One slip in concentration, and Lionel Messi, or Andres Iniesta, or Xavi, are going to wreak absolute havoc. They're taking their chances, but thus far, Milan have kept the ball hitting the side of the net rather than the back.
