Former world number one Andy Roddick has insisted that he does not have any regrets over his decision to retire from tennis in September.

The 30-year-old, who beat Andy Murray in an exhibition match earlier this month, has admitted, however, that he does miss preparing for tournaments.

"To be honest, I don't know that it will really affect me until January comes around. The last 13 Januarys I've been in Australia. I haven't experienced January 8 in the United States for 15 years," Roddick told ESPN.

"You start to identify certain months with certain places, that's where you are. I wasn't jealous of the guys going on a 15-hour flight to Shanghai or wherever else. Once I see the guys over [in Australia], obviously I'll miss it a little bit."

Roddick secured 32 titles during his illustrious career.
