You say this as if Rodger didn't win the Australian Open this year...Federer is already in decline, isn't he? Has been since 2008 TBH, though he was managing to peak during Grand Slam tournaments until this year. The bad news is Nadal looks like a bigger, badder version of Federer in his dominating days.
Is he in decline? Yes. Is he not going to win another slam? No.
