It's now or never for Murray. No Federer or Nadal on the other side of the yet, and he has gone through all the razzmatazz of an Australian Open final already last year.
Djokovic is playing very well, and must be close to overtaking Federer as no. 2 in the world, having now beaten him twice in succession in Grand Slam semi-finals. But really, if you'd offered Murray a place in the final against Djokovic, he'd have bitten your hand off. He couldn't ask for a better opportunity.
