This What Delpotro said about Federer :
"You've been playing great tennis this year. You are in fantastic shape, it's unbelievable, I would love to be at your age in the same form, but I don't think so."
"You've been on a great run since the US Open and before so I'm very happy to see you playing so well again and being able to play every week. That's something I would like to be able to do again, All the best for Paris and then I'll hopefully maybe see you in London, too."
