Carlos Moya believes Rafael Nadal lost out at the ATP Finals because Dominic Thiem and Daniil Medvedev managed the crucial moments better.
Nadal played some brilliant tennis at the ATP Finals despite losing two matches in the week.
It leaves the Spaniard still searching for his first title in the tournament, although his coach Moya says his opponents deserve credit for what they were able to do to him.
"The ATP Finals was a pity, as I think Rafa had chances of reaching the final and battling for the title," Moya said.
"Those tense moments usually work in his favour, but that wasn't the case against Daniil Medvedev and Dominic Thiem.
"Things are developing quickly on such a fast court like in London, and two or three key moments will decide the winner among the top-ranked rivals.
"You have to stay focused and grab those crucial points, as they are likely to determine who takes the victory home.
"Usually, Rafa solves this type of situation in his favour, but we have to praise Thiem and Medvedev, whom both played on a high level when it mattered the most.
"They won the crucial points against Rafa and came as deserved winners."
