LONDON — Rafa Nadal will be pose a significant grand slam threat again next year after showing signs of returning to his best, according to two of the Spaniard's greatest rivals.
Spaniard Nadal slumped to 10th in the world rankings this year after a crisis of confidence and form, but since a third-round defeat at the U.S. Open by Italian Fabio Fognini he has rediscovered his old spark.
So far this week at the ATP World Tour Finals he has beaten world number four Stanislas Wawrinka and number two Andy Murray, without dropping a set to reach the semi-finals with a match to spare, where he will face world number one Novak Djokovic.
