Rafael Nadal who failed to retain the Argentina Open title said that he is not worried about the defeat.
Nadal reached the semi-final of the clay-court tournament, but could not progress any further as he suffered a 4-6 6-4 6-7 defeat to Dominic Thiem on Saturday.
“It was a tough match.
“I had a chance to win and missed it but Thiem played well.
“I’m not worried. I just lacked consistency and need to make fewer unforced errors, but that’s nothing,” Nadal claimed.
