Looking at Nadal vs Thiem Prediction, defending champion Rafael Nadal acknowledges that he must improve his underwhelming performances if he is to defeat Dominic Thiem in the US Open quarter-finals.
Nadal has struggled past Karen Khachanov and Nikoloz Basilashvili at Flushing Meadows, but the top seed faces a very different prospect against French Open finalist Thiem in the last eight.
While Nadal was able to celebrate a clean sweep of grand slam quarter-finals in 2018 on Sunday after edging past Basilashvili 6-3 6-3 6-7 (6-8) 6-4, he was under no illusions about the scale of the task ahead of him.
"I am in the second week already. That's a positive thing," the Spaniard told a news conference. "I have been in the quarter-finals in all grand slams. I hadn't done that since 2011, so that is a positive thing.
Thiem defeated last year's runner-up Kevin Anderson in the fourth round and won one of three meetings with Nadal on the 17-time major champion's favoured clay surface earlier this year.
