I think he should during the transfer window for the 2 months or so before MLS starts up. I hope someone picks him up. At the very least I hope he goes over there to train .
He just signed an extension with KC I believe through 2017 or something. He isn't a designated player, but he is getting paid well( by mls standards).
I know he has come out and said that he wants to play in Europe. I'm all for our players going to play in Europe, as longs as they will get playing time. Brek Shea went to Stoke , and he hardly ever plays, terrible decision by him(Klinnsman even told him it was a bad decision and he went anyway). It's tricky with our players, they have to be careful when going to Europe, there is no point in going over there to not play.
I like Zusi too, but assuming everyone is healthy I don't think he would start on the USMNT, Donovan is ahead of him on the depth chart.
