Sharapova 'still can't believe' Wimbledon triumph

Wimbledon champion Maria Sharapova has labelled the last year "amazing" as she launches the preparations for the defence of her title.

The 18-year-old starts the countdown to her return to Wimbledon in Birmingham this week when she will be seeking to retain the DFS title she won at the Edgbaston Priory 12 months ago.
