Not many people know that Richard Williams has already left London as the sight of both his daughters slugging it out at the World's best stage is something the emotional father can not bear. The sisters, on the other hand, have now become so used to facing each other in the major finals that once they are on court, they reach for each other's throats before they go for a hug.  As Wimbledon awaits another sister final, fourth to be more precise, we take a look at the contendorship of both the stars at this year's Championships -

Venus Williams vs. Serena Williams
Head-to-Head
Series tied at 10-10
Last Meeting - 2009 Sony Ericsson Open Semifinal
Serena Williams won 6-4, 3-6, 6-3

Five time champion Venus Williams holds an extraordinary 35 set win streak going into the final, whereas two time champion Serena Williams boasts of an emphatic win in the sister's last encounter in Miami. The facts could go on and on but nothing can possibly help in determining who has an edge over whom while going into the final on Saturday. But still if the statistics are to be analysed, then here is what needs to be taken into consideration. Both sisters have played each other four time at the All England Lawn Tennis Club, with Venus winning the semifinal encounter in 2000 and final triumph in 2008 and Serena picking up victories in 2002 and 2003 finals. Further, they have met each other twice this year, with both splitting the wins in Dubai and Miami respectively. The only factor that may give Serena a slight edge is her overall lead against the elder sister in the slam finals. Both have contested seven major finals with Serena leading the tally 5-2. But then again, it's Venus who won the duo's last slam encounter at the same stage a year ago.

The truth is that the deeper we go into these statistics, the difficult it becomes to predict a winner. Seven time champion Steffi Graf had once mentioned in her interview in 1998 that Venus Williams has the potential to become a Wimbledon great, and that she will one day rule the tennis world. Graf's assessment of the elder Williams turned out to be remarkably true as with an appearance in her eighth Wimbledon final, Venus is already on the verge of joining the elite group to hold the Venus Rosewater Dish atleast six times in her career. The only other women to achieve the 'elusive feat' in the Open era are Martina Navratilova (9), Steffi Graf (7) and Billie Jean King (6).

Serena's biggest asset on the other hand is her fiesty competitiveness that has seen her bounce back in the matches from the brink of defeat. Serena, who has already saved a match point in her semifinal match against Elena Dementieva, is looking hungrier than ever. Already touted by many as the best tennis player of her generation, the 10 time Grand Slam champion will do anything to win her third title at the All England Lawn Tennis Club.

Even though the sisters have played so many major finals, the best out of them was showcased at Melbourne Park in 2003, where Serena completed her Serena-Slam by beating Venus in three closely contested sets. Only time will tell how many Grand Slams both will end up with, but for now, the last thing everyone is expecting is another lopsided All-Williams final and with such ambitious approach, both sisters will enter the centre court at the SW 19 to romance the silverware with their own name on it.
