Dominic Thiem says he has now fully recovered from the physical and mental exhaustion he experienced at Roland Garros earlier this month.
Thiem went to Paris direct from winning the US Open, and by the time his epic quarter-final match against Diego Schwartzman was over it was clear that his efforts had taken their toll.
After two weeks rest, though, he says he is back and ready to go again - starting with Vienna.
"I recovered well for a few days at home and for once did nothing. It took a while to get back to my physical level, but I would say that I am fully back, both in my head and body.
"It just took a little time after Paris to be able to reflect on everything. I am so grateful that we can play here at all.
"Obviously I was completely done after the French Open, so I took off a week where I did nothing and I also had to still reflect on the US Open title.
"Then [I] set myself new goals, of course looking forward to the tournament in Vienna, which every year [has been] a special highlight since I [was] a young kid, since I played here for the first time."
Thiem is the defending champion in Vienna, and it's one that is obviously very close to his heart.
"After the US Open, it's the biggest title [I've won] and one of the most emotional.
"Starting a tournament as defending champion is always something special. This year it's even more special.
"The field here is so strong, maybe the best ever in an ATP500 tournament."
