Roger and Mika get along very fine.
Marco might well be a very nice guy off-court (and from personal experiences I can fully agree with that), that doesn't mean he's very nice ON court as well
Llodra didn't say anything about that. Anyway, as for on-court attitudes many things can be said for everybody, including Llodra's attitude with the ballkids : maybe I shouldn't have talked about it, that was not the topic.
Actually informations on-site in Marseilles rather talked about Chiudinelli taking Llodra's favorite locker in Roland-Garros and Llodra getting angry about that. Llodra sounds funny and quite nice to me hearing him often in France, but he also sounds nervous and childish, and tennis players are very superstitious, then I can guess a quarrel started with something like that.
As for "Roger and Mika" getting along fine, I don't know but if there was such a quarrel between one of my best friends and another guy, I don't say I would be mad at that guy and I actually think Fed and Llodra will be very professional today, but at least I wouldn't feel that comfortable to be that friendly with him as last time Fed and Llodra met. That's all I meant to say actually, that we shouldn't expect the match to be as nice and friendly as last time
