In an interview to US Open.org, former Andy Murray's coach Brad Gilbert commented on Novak Djokovic's US Open chances. The Serb seeks his fourth title in New York after 2011, 2015 and 2018. "He just has a great ability to focus on what's in front of him", said Gilbert.
"A lot of times that stuff can fuel you, but if you don't have the ability, it doesn't matter. His ability and when he's playing at his level, it's just insane. He plays just a lot of quality shots, and he doesn't make unforced errors, and he makes you have to beat him.
He plays cross court so often to big targets, but yet he's making progress. You start to look at him, like, 'Uh oh, he's in lockdown mode.' And if he's in lockdown mode, see if you can win a set. I don't know if he has a best or worst surface, that's how good he is.
If he's totally playing at his highest level, I've never seen anybody, from a courtside position, from where I sit and where I watch, that plays better than him."
