Florent Serra was in a good form two months ago, now he isn't playing well. Gillu can crush him
Rather the other way around imo, Flo has been in horrid form this year, but he has shown some improvement in the last 2 months.
They know each other so well with Flo, I would have preferred him to play somebody else. But Gilles should definitely win, of course. After having played the qualies, he must be motivated to win a couple of matches there, and he was looking fine to me yesterday.
