Oh yes he is.
When his records go, he won't be remembered as #1 any more. So he has to pretend that the records aren't really going, that Fed's records are somehow "fake." Where do I see this? In just about everything he says. There are sly little digs all over the place - you don't have to look hard! (and other interviews have been worse than this one - at least here he pretends to be gracious). Examples of "sly little digs":
"People have mentioned to me: You should come back. There's not many great players today"
"He's winning these majors with pretty much ease. He's not challenged much."
"If there were three or four guys who were pushing him..."
"I don't see him slowing down or anyone slowing him down." (liked this one - "or anyone slowing him down")
"I would attack his backhand, which is his weaker side, and go from there. Unfortunately, we don't have anyone who can do that today" - this one is particularly silly as there are several players on tour with better backhands than Pete who have tried and failed to break down Fed's B/H. I mean Hewitt used to out-backhand Pete for god's sake. Federer's B/H is far superior to Pete's.
"James Blake is No. 6 in the world and I wonder what it would be like to play him at this stage of my life if he gave me a few months to prepare." - Translation: Even at 35 I can beat that sucker.
Well, put your money where your mouth is, then! The Wimbledon W/C is waiting for you. If it is true that you can take out the world #6, you can certainly do some damage there. Better than being a bitter old man sniping from the sidelines.
"It is crazy the amount of power a guy like Fernando Gonzalez can get from that racket. It has made mediocre players better..." Translation: He is a mediocre player with a good racquet
. I don't think this one is really on. Gonzo is not mediocre, he was posting winner/ UE stats at the AO that I can't remember Pete ever getting close to (although of course it may just be the racquet!)
