Novak Djokovic says that securing the year-end world number one spot 'affected him' in his shock defeat to Lorenzo Sonego.
Djokovic took a wildcard to enter the ATP500 in Vienna, knowing that two wins would get him the points he required to be certain of being crowned the year-end world number one for a record-equalling sixth time.
He achieved those two wins earlier in the week, yet was still heavy favourite to beat lucky loser Sonego in the quarterfinal.
However, he looked disinterested from the off, quickly finding himself 0-4 down in the first set before losing 6-2, 6-1.
It was the joint worst defat of his career, and the only time he has ever lost to a lucky loser. He, though, says it was a case of job done and he will be leaving Vienna a happy man.
"Yes, clinching the [year-end] number one had an effect on me today," Djokovic admitted.
"I’ve done what I came here for, securing the number one. And I move completely fine with today’s result.
"I'm healthy and looking forward to a strong finish in London."
