I didn't know Chiudinelli plays interclubs, somehow it always seemed exclusively French to me, unlike the German bundesliga which has tons of foreigners.
I haven't followed the interclubs this year, but at the 2010 championship, the teams were as follows :
Rennes (A.Seppi, S.Bollelli, S.Greul, B.Phau)
TC Paris (JW.Tsonga, S.Wawrinka, M.Chiudinelli)
Colombiers (M.Zverev, M.Granollers, D.Gimeno, R.Machado)
Toulouse (J.Chardy, O.Hernandez, P.Starace)
Lille (V.Hanescu, B.Becker, O.Rochus, X.Malisse)
Bressuire (V.Troicki, I.Kunitsyn, O.Dolgopolov, I.Dodig)
Blagnac (F.Verdasco, F.Gonzalez, T.gabashvili, S.Stakhovsky)
Metz (P.Kohlschreiber, P.Petschner, D.Istomin, J.Nieminen)
Bordeaux (J.Hernych, M.Llodra, S.Darcis, B.Paire)
Paris Racing was the only all French team (G.Simon, R.Gasquet, J.Benneteau, N.Mahut).
