No, he's #4 now, but I agree that his performance wasn't all that great. Too much dependency on his serve and very little variation in his game. I never did understand why he split with Moya, unless it was Moya who instigated it.
McEnroe was apparently doing some snarky gossip on ESPN during the AO and claimed Carlos split with Raonic because he didn't want to travel so much. McEnroe seemed to think that now Carlos is with Rafa he basically lied to Milos. But given that Carlos won't have to travel abroad for training blocks with Rafa and won't be travelling as much with Rafa this year as he did with Milos last year I can't see any lies.
It turned out that Milos actually twice approach Krajicek for coaching - before Moyà and again for the grasss season but whatever Milos was offering in terms of time didn't work for Kraijcek, who then works with Stan during a very lacklustre stint on grass. Mills is currently being pretty lacklustre as well.
