Serena Williams may be on the verge of making history at Wimbledon, but the stress-free former champion insists she doesn't feel under any pressure. Serena reached her 35th Grand Slam semi-final with a gritty 3-6, 6-3, 6-4 quarter-final win over Camila Giorgi on Tuesday. The American star faces German 13th seed Julia Goerges today hoping to book a 10th final appearance at the All England Club.

Serena, a seven-time Wimbledon winner, was outwardly full of fire as she shrieked her way to victory against the unseeded Italian. But beneath the surface, Serena insisted she is feeling unusually calm as she enters the business end of the tournament. "It's weird. Sometimes I feel, 'Man, I'm in trouble'. Sometimes I feel I can fight. For whatever reason, I was so calm," Williams said.
