But none of those routes was as demanding as Delpo-Murray/Nole-Nole/Murray though.
You have to remember the group A semifinalist he will face will be very well rested (at least 48 hours), which is an extra disadvantage. None of this would be a problem if Federer was in his prime, but he isn't - at his age, recovery from match to match doesn't come as easy.
