It's hard to imagine Sania Mirza as the 'mamma's girl' she claims to be. In public, she is diva-like, cocky and brash, with her devil-may-care attitude sometimes putting-off. So, when she reminisces about the time when her mother forced her to gulp down four glasses of milk a day, one can barely suppress a snicker.

"I think drinking four glasses a day was a bit too much but my mom asked me to and I was an obedient girl," Sania said during a promotional event in the city on Friday. Now we know where the power of her forehand comes from.

Sania, who had an indifferent 2008 plagued with injury, made a spectacular comeback in the New Year, winning the Australian Open mixed doubles title with Mahesh Bhupathi. She reached the final of the Pattaya Open earlier this month where she went down to Russia's Vera Zvonereva. To keep up the momentum and get back into top 30 singles players in the world, Sania is concentrating on her fitness and travelling to the United States on Saturday to train with Gil Reyes, the man credited with Andre Agassi's rebirth in the sport.

"Reyes has worked with Agassi and Verdasco (Fernando) recently. Hopefully he can help me too. I am leaving on Saturday," she said.

A Grand Slam in doubles, could that imply that her singles career will take a back seat? "No. On the contrary, I am more focused on singles. But playing both doubles and singles can sometimes take a toll. I might miss a few doubles tournaments to focus on my singles game," she said.

Having achieved her dream of winning a Grand Slam, Sania said her goals have changed. "I like the way my career is going. I am greedy by nature and my goals keep changing. I won't be more specific than that. But let's see how things go," Sania said.

The Hyderabadi, who idolised German legend Steffi Graf when growing up, said the support of her mother, Nasima, during the difficult last year helped her to cope. "My mother was always there to support me. She pushed me harder than I would have ever pushed myself. I owe my success to her," Sania said.
