Perhaps the most troubling of all the Silver stage skill games was the Lob Pass skill game. For this I recommend using Xavi or Iniesta (best passing stats in the game) and using your first 3 attempts to chip the ball into any of the front 3 bins by holding LB and then gently pressing the cross button (B for me). Once you've hit 3 attempts in a row into the bins (netting you a 3x multiplier) you must, in your first attempt, get a ball into the group of bins furthest away by maxing the power bar on the cross. This should net you a score of 20000+ (20000 needed to pass Silver!).
