Next big thing? 'Whatever', says Muguruza

Young Spaniard taking new-found fame in her stride

In-form and highly marketable Garbine Muguruza says she is flattered and not burdened by talk that she has what it takes to succeed Serena Williams as the next big thing in women's tennis.

The 22-year-old Spaniard has steadily risen through the rankings since 2010 to a career-high three, and gets her Australian Open underway on Tuesday against Estonia's Anett Kontaveit.
