Sacha Kljestan Being Courted

The clubs reportedly interested in Chivas USA and U.S. International Sacha Kljestan are (with my thoughts)

Celtic (Scottish Premier League)--intersting possiblities in Old Firm Derbies with DaMarcus Beasley and Maurice Edu, but other than that this would be a bad move for Kljestan.
Monaco (Ligue Un)--With the talented Freddy Adu not getting playing time, I am wondering if Monaco be the best place for Kljestan. The two men have different playing styles in some ways, and Kljestan is bigger and stronger than Adu, but perhaps not as creative.
Heerenveen (Eredivisie)--I always thought Kljestan would benefit from the attacking, tactical style of Dutch football. Heerenveen is a quality club and I could see Kljestan really blossoming there. The tactics and attacking play of the Dutch will make Kljestan a better player internationally, and he is easily on Bob Bradley's call up list.
FC Twente (Eredivisie)--I am not a big fan of Twente's manager Steve McClaren, but he is helming Twente to a quality start and with the wide open Eredivisie, playing for Twente or Heerenveen is a good move.
Leverkusen (Bundesliga 1)--I don't know about what kind of role Kljestan would fill at Leverkusen and I am not sure how much playing time he would get.
Schalke (Bundesliga 1)--Ditto for above, but I think Kljestan's style of play fits more at Schalke more than Leverkusen.
Wolfsburg (Bundesliga 2)--Kljestan should not move to Bundesliga 2, it is not as much of a move up as he could benefit from and Wolfsburg does not look like they are knocking on teh door of promotion.
Greek Olympiakos--Interesting, but really, should a top U.S. International go to the Greek league? Yes, they play Champions League a lot, but I don't think Kljestan should go to Greece just to get Champions league when the domestic league won't test him enough.
Zenit St Petersburg--again, a neat idea, but I don't think this is a good move for him.
