For what it's worth, Fed looked totally disinterested in the Dubai final. In fact, he looked as if he couldn't be bothered. So many unforced errors - really not like him. Djokovic played sublime tennis - a joy to watch, and he seems like a sporting guy. Lots of sporting stuff to see live that I assume gets lost on TV.
Maybe Fed's only interested in winning Masters, or more importantly, a few more GSs to add to his haul. Anything else is probably beneath his dignity now.
