Dominic Thiem defeated Marin Cilic 6-2 6-2 3-6 6-3 at the US Open to reach the next round and after the match, he spoke with the media. When asked about his fast start he explained it:

"I think the quick start was more because of him. He had two very tough rounds and was a little bit slow in the beginning. I took all of my chances. Today was a good win against a great champion, so that should give me a boost."

Thiem then proceeded to talk about his own level and preparation admitting he wasn't yet where he wants to be but he is getting there:

"I'm not 100 per cent yet. I still have to raise my level if I want to go deeper. I'm normally capable of doing this in the Slams [and] hopefully here as well."

His next match will be against Felix Auger-Aliassime who is enjoying a stellar US Open campaign and speaking about him Theim said:

"The whole package is great. He's a great player, great person outside of the court. I think he has huge star potential. Unbelievable athlete, good looking. He has everything basically. The only thing to my advantage is experience. This is his first fourth round at a Slam, so hopefully I can play that out a bit. It's going to be a nice one and I'm looking forward to it."
