There's some good news for today to lessen the loss of Gonzalez: Timothy Tillman, a German U-20 prospect, has switched allegiances to the United States. Plays for Bayern at the club level.
USMNT news: Bayern's Timothy Tillman ready to join U.S. U-20 team, says Tab Ramos | Goal.com
He's HIGHLY rated by both Bayern and the German National setup. Sees a lot of time with Bayern II (their U-23's) already. Didn't think we'd even sniff him after he played some German U-20 Euro qualifiers in September. This is a major, awesome, and unexpected turnaround. Has a younger brother also in the Bayern youth system that's part of our national setup already.
EDIT: Admittedly it's tough to rate these younger players (see: Green, Julian) but if you're going to be upset about Gonzalez you better be happy about Tillman.
