A few bits about Gilles from articles about the tournament:
An article about his first round match:
I didn't know Frank speaks French too.
Gilles says about him that he's very difficult to play because he can come out with incredible shots. They've never played before, but he's often seen him give a hard time to good players, like in Montreal to Nadal.
The win over Fed in Toronto last year was a big triggering experience for his career, even though the Madrid match against Nadal was his most accomplished performance.
"I'm trying to get back to my best level. It implies to recover my footwork to make it very difficult again to hit a winner against me, which wasn't true anymore lately. My knee prevented me from practicing the way I wanted it, I was able to practice only 1-2 hours a day. I took some time off and I hope to be back to my best level now."
He practiced with Rafa:
He won one set 6-2, huge confidence boost for him since we now know practice sets mean a lot to him. ^^
Here he says that he would have gotten a bye if either Nadal or Fed decided not to play, but he preferred them to be there. Tournaments really feel different when they're not there, for the crowd and for the players too.
And this one is about French tennis in general:
The journalist is drooling big time over this generation of French players, how successful and cool and nice they are, etc.
Jo, Gilles and Gaël were all coached during their Juniors times by Borfiga who now is in charge of Canadian tennis, but used to work for the French Tennis Association at the time, so he has a special connection to them.
It's more about Jo, but there's a short quote of Gilles at the end too saying that Montreal is a particularly nice place for French players and he loves it there.
