If Roger only cares about the slams then why did he fight so hard to win Paris just a few months ago? He obviously has a tennis bucket list that he's after.
Fed's finding out that you can't just try to play good at slams.
You need to push all the time to keep in top shape.
Look at Nole last year and the years Fed did so well, they both put a major effort in at all tournaments.
Fed is working hard at all tournaments now, I get a little worried that it may be too much, he isn't 25 anymore.
But as I stated above, it's very difficult to just turn it on at majors.
The smaller tournaments is where a lot of confidence gets built, once that's there then it carries over to slams.
