have we got a federer-nadal era style of domination coming up these next years ?.
Pretty much. On clay I would see Murray as still only being the 4th or 5th best, and on grass see Djokovic as only the 4th best or so . On hard courts, all speeds, Djokovic and Murray will be the ones to beat.There's a time and place for Djokovic/Murray to dominate.
On clay? Probably not Murray
On grass? Probably not Djokovic
But hardcourt, 70% of the tour, most probably yes. I'm sure when Nadal's back he could beat Murray on the off or whatever.
