Madrid: Rafael Nadal's former coach and uncle Toni Nadal on Friday said that the former World number one in ATP rankings could clinch Nitto ATP Finals.
Toni also said that the Spaniard has been training well, something that should help him finish the season strong.
"Rafael could win the Nitto ATP Finals in London," he said, before adding, "It is going to be very difficult because there is Medvedev, Djokovic, Federer".
Toni Nadal, who was taking part in the Motivation and Entrepreneurship Forum, said that the player approaches the final stretch of the season "in very good condition."
"I trained him for a day to replace Moya and I thought he was playing very well," he added.
The 50th edition of the ATP Finals, formerly known as Tennis Masters Cup, will take place in December at London's O2 Arena.
The ATP Finals title has so far eluded Nadal, a 12-time French Open champion.
Asked about the Davis Cup, Toni Nadal expressed his gratitude to Barcelona defender Gerard Piqué, whose company is an organizer, for the new format.
The previous format was "inviable", Toni Nadal said, lamenting that the International Tennis Federation "never made a change to make it easier for the best players to participate."
The schedule and the change of surfaces were the main issues.
"You play in Miami one week, then you move to Australia and then return to Monte Carlo, there are three different surfaces in two weeks," he added.
