Galaxy 4 DC 1
Well, we found out!
It was the Magical Mike McGee Homecoming (LA Galaxy 2009-2013) Tour. He scored two goals, assisted in one, and drew the PK for Keane to slot in.
The line-up in the second half, when the Galaxy got all its goals, was somewhat different than what "plan A" was supposed to look like. Given the reality of injuries, it is good to know that Arena can plug in a plan B and win matches!
