Fed was the better player, while Novak was more clutch. That's it.
Novak deserved to win, but Fed choked really hard and eventually gifted him the win.
You are right Novak was more clutch. But you gotta remember you don't get a bonus set for losing a tight set 7-6 and winning the other 6-1. Its still 1-1 in sets.
Djokovic scored one point more than Federer in set 1, in set two there was a substantial difference in points won in Feds favour. Set 3 was again very even and a point seperated them. So it was a very tight set and it came down to clutchness in the TB, and Djokovic was much better than Fed in that TB. As a matter o fact, in all TBs Djokovic was the much better player. Set 4 Federer wins 5 points more wich isn't that much more and finally set 5 Djokovic edges it with 1 point.
Looking at the overall stats sure you could say Federer was the better player, but Id say that is mainly cause of set 2.
The unlucky part for Fed was that he couldnt get an ace or hit a great first serve, but that isn't choking.
In total they played 33 points across all TBs, and Djokovic didn't make a single UE.
And don't forget Djokovic was up a break much earlier than the 2 CPs. And in that game he was spraying errors everywhere.
All in all, it was a very even match with both players having opportunities to close it out, but it came down to no choke.
