Juan Martin del Potro is revelling in his first win at this year's ATP World Tour Finals.
The Argentine overcame Janko Tipsarevic 6-0 6-4 to open his account at the London tournament, and admits that he is relishing each game in the UK capital.
"I'm so glad to be part of this amazing tournament. I have good memories from being here in 2009. I'm trying to play my best tennis. I'm really enjoying this week," BBC Sport quotes him as saying.
"It's not easy to win a set 6-0. Janko was fighting. He's a very good player. I have a high step up against Federer on Saturday but I will try to beat him.
"I have worked a lot every day to be here [after my injury problems]. I made a good comeback last year. I'm back in the top 10. I really want to enjoy this week."
Del Potro will take on world number two Roger Federer on Saturday.
