For me is veeery easy to make the argument that this isn’t psychological, but only to the expected variance of tennis match results. It was you that had to carefully cherry-pick data to support your conclusion. I would only have to choose among all the other match points he has won through the 20 grand slams he has won. Only considering Federer vs Djoko, Federer won 46% of the matches. There a lot of match points won there. Also, considering only Grand Slams, Federer won 6 out of 17. Not a great record, but still no negligible number of wins. And I would attribute that bad performance more to Djoko skills, and maybe also Djoko physical peak coinciding with Federer older age, than to any thing psychological.
