Carlos Bocanegra is off to France
Rennes are a good French side, but not one the of the best. They have made it to the UEFA Cup twice in the last 3 years, however both times they failed to get out of the group phase.
The good side of this is he will get a lot of playing time. The bad side, the French league doesn't have the same top-quality players as the EPL or the other top leagues in Europe.
Still, congratulations to Bocanegra and good luck learning French. By the way, Rennes is about 210 miles west of Paris.
