*Fourth all-Williams final at the All England Club

(Adds details)

LONDON, July 2 (Reuters) - Venus Williams will play her sister Serena in Saturday's Wimbledon final after a crushing 6-1 6-0 victory over top seed Dinara Safina of Russia on Thursday.

Venus's place in an eighth final, and fourth against her sister, was never in doubt as the Russian failed to come to terms with Williams's powerful hitting from the back of the court in a match which lasted just 51 minutes.

"This is my eighth final and a dream come true to be here again and have the opportunity to hold the plate up," the five-time champion said in a courtside interview.

"She's (Safina) so talented and she's played so consistently in the last year and I went out there and was able to really stay focused. I have so much experience on this court it helps a lot."

The match opened before a half-full Centre Court as the crowd sought shade and refreshment after Serena's almost three-hour victory over Russia's Elena Dementieva in the day's first semi-final.

Venus didn't seem to mind the lack of attention as she raced to a 5-0 lead and sealed the opener after just 27 minutes.
