Novak Djokovic said winning a record-equalling sixth ATP Tour Finals title on Sunday was a "deeply satisfying" ending to his troubled and truncated year.
Novak Djokovic will have his visa ban overturned and will be able to compete at the Australian Open, according to reports in the country.
Rafael Nadal said he was slow and rusty as he suffered a disastrous start to his bid to win the ATP Finals for the first time after crashing to a 7-6 (7/3), 6-1 defeat to Taylor Fritz on Sunday.
