LONDON - Serena Williams sent a warning to her Wimbledon title rivals as the world No.1 completed her preparations for the grasscourt 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 press conferences on Sunday, 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.
Williams has been mired in something of a slump of late following surprise exits from both the Australian and French Opens.
Although she has won titles in Brisbane, Miami and Rome, the five-time Wimbledon champion has also suffered underwhelming losses to the likes of Petra Kvitova, Jana Cepelova, Ana Ivanovic and Alize Cornet.
Serena's struggles have prompted some to suggest she is finally in decline.
But those chastening defeats have only strengthened her desire to make amends in south-west London and few would bet against the ferociously competitive American adding a sixth Wimbledon singles title to her glittering CV by the time the women's tournament comes to a conclusion on July 5.
