Stefanos Tsitsipas says he has 'grown up' since he won last year's ATP Finals as he prepares for Vienna.
Tsitsipas is part of a stellar line-up in Vienna as he works towards defending the ATP Tour title he won in London last season.
He, though, believes he will head to the O2 a better player - and person - than he did last year.
“A lot of things have changed [since the ATP Finals]," Tsitsipas said ahead of his first match in the Austrian capital.
"I think I’ve grown up and faced pain on and off the court. So there were a lot of lessons to be taken and I had a lot of matches since that time but not as many as I hoped to have due to COVID.
“Right now, I’m not thinking about the [upcoming] ATP Finals. I’m focusing [on] this week and then next week in Bercy.
"I feel like these are tournaments that I can do better [at] this year and have a better version of Stefanos on the court, so I’m glad that I’m here.
“I’m glad that we get to play these tournaments given the current state of the world.”
Tsitsipas initially struggled coming out of the enforced coronavirus break, losing at the US Open to Borna Coric before struggling badly in Rome.
He has since found some exciting form, though, reaching the final in Hamburg and the semi-finals of the French Open. He, though, says his struggles were down to experimentation.
“It was a period where I was trying and testing new things,” he explained.
“I just happened to try these new things during the US Open swing and Rome.
"Then I went back to my old ways and I started feeling more comfortable and confident on the court after that.”
