Djokovic has a lot of pressure at the AO next year because so far he hasn’t won a slam since the pandemic. Will it become a mental block? Time will tell.
Also Federer will most likely be back, Nadal will be confident, Thiem is motivated, and so many of the young generation players are starting to come into their own.
I still think that Djokovic has one more slam in him but things will become more and more difficult.
