Rafael Nadal has praised Novak Djokovic after the world number one won their last-four clash at the ATP World Tour Finals.
Djokovic failed to produce his best tennis towards the end of the round-robin stage, but he was superb as he ran out a 6-3 6-3 winner against Nadal at the O2 Arena in London.
The 29-year-old is quoted by BBC Sport as saying: "He's hitting amazing. The return was always amazing. This year he's serving great, I think.
"When somebody's doing like this, the only thing I can do is congratulate him and just wish him not the best of luck for the next year."
Djokovic will play either Roger Federer or Stanislas Wawrinka in Sunday's final.
