Surly Serena in no mood for small talk

Serena Williams sent a warning to her Wimbledon title rivals as the world No 1 completed her preparations for the grass-court Grand Slam in a feisty mood.

With Wimbledon set to get underway on Monday, Williams made an appearance at the All England Club's pre-tournament media conferences on Saturday, but it quickly became clear the American had no time for small talk.

The 32-year-old cut a grumpy figure for much of her brief session with the media, issuing short answers to many questions and showing little of her usually effervescent personality.
