Nadal and Djokovic lose semi-finals

Rafael Nadal's dream of adding the ATP Finals title to his vast collection of silverware has ended for another year as the Spaniard was beaten 3-6 7-6(4) 6-3 by Russian Daniil Medvedev in a sizzling semi-final in London.

Medvedev's first career victory over the 20-times Grand Slam champion sent him through to a final showdown against Dominic Thiem who earlier beat Novak Djokovic in another titanic clash.

The 24-year-old Medvedev reached the semi-finals as the only player to post a 100% record in his group, including a superb defeat of Djokovic.

Thiem will attempt to go one better than last year when he lost to Stefanos Tsitsipas in the final.

Defeat means Djokovic will have to wait until the event moves to Turin next year, after 12 years in London, to try again to equal Roger Federer's six titles at the year-ender.
