Williams fends off spirited Muguruza in women's final to complete 'Serena Slam'

In winning her sixth title on Centre Court at the All England club and her 21st Grand Slam title, the world number one holds all four Grand Slam titles - the Australian Open, the French Open, Wimbledon and the US Open.

Muguruza subjected Williams to a 6-2 6-2 pummelling at last year's French Open, and managed to rally from 5-1 behind in the second set to close to 5-4 before the American broke back to love to prompt scenes of relief as much as joy among her family and coaching team.

"It feels so good. It has been a little while," said Williams, who defeated sister Venus in the final to win her first Wimbledon 13 years ago. "Garbine played so well. Congratulations, don't be sad, you will be holding this trophy soon.

"I can't believe I'm standing here with another 'Serena Slam'. It has been a pleasure and an honour to play so many years in this unbelievable stadium.

"I'm having so much fun. Every day is a pleasure to be out here, and winning Wimbledon."

She will complete the calendar Grand Slam for the first time if she defends the US Open next month.

At 33, she is the oldest winner of a major in the Open era, and is one behind the modern day record held by Germany's Steffi Graf on 22, a total she can equal if she emerges victorious at Flushing Meadows in New York.

Graf was the last women to carry off the calender Grand Slam back in 1988 when she also won Olympic gold.

Williams was tested early on and in the second set against her 21-year-old Spanish opponent, who was just five when Williams lifted her first major trophy at the US Open in 1999.

But she was simply too good in the key moments in completing her second 'Serena Slam' - a feat she managed at the Australian Open back in 2003.
