She is beautiful, a powerhouse of strength and ferocious talent with the mind-set of a battling champion.

On Saturday 11 July, the world will watch as Serena Williams - the world number one in women's tennis - takes on Garbine Muguruza in the women's singles final clash of the 2015 Wimbledon after defeating rival Maria Sharapova in straight sets 6-2, 6-4.

While Paddy Power has offered odds of 1/5 on Williams emerging triumphant , there is a good chance that Muguruza, who is Spain's first female finalist since Arantxa Sanchez-Vicario in 1996, won't make it an easy ride.

The 21-year-old beat Williams 6-2 6-2 in the second round of the 2014 French Open and knows she has the power to end her idol's Grand Slam dream this time around.

Williams, who started out her career in the late 90s, recently admitted that the defeat her opponent inflicted upon her last year was a catalyst for soul-searching, resulting in her impressive form over the last 12 months.

"It was an eye-opening loss for me," Williams said of the defeat. "Some losses you're angry about, and some losses you learn from. That loss I think I learned the most from in a long time."

While Saturday's clash is unpredictable, there are many reasons why she could still charge to victory.

At 33, what Williams lacks in youth, she makes up for with natural ability, experience and an admirable work ethic. This is her 16th appearance here at the Wimbledon Championships and she remains on target for a clean sweep of the 2015 Grand Slam titles.

She has 67 tour titles including six Australian Open, Three French Open, six US Opens and seven Wimbledon wins under her belt.

In contrast, Muguruza was just five when the US tennis champ, who loves nothing more than pummelling her rivals, won her first grand slam at the 1999 US Open, under the training of her father Richard Williams, who also coached her sister Venus.

"She has the best serve of all time. And she is super-powerful and hits winners from both sides. If you have all those things, you are a really special champion," Williams coach Patrick Mouratoglou recently told the Daily Mail.

"She refuses to lose and she gets so dangerous when she is close to losing because if she thinks she might die, that is when she digs, when she finds something to raise her level to a height no-one else can compete with."

While Muguruza is relatively new to the game, Williams has established a strong fan base over the past decade during her prolific rise to the top. During the tournament Williams' box at SW19 has boasted an impressive entourage of celebrity fans including rapper Drake, models Chrissy Teigen and Karlie Kloss as well as Dasha Zhukova, Roman Abramovich's wife.

Her relationships have been equally high-profile. She is said to have briefly dated Bulgarian tennis pro Grigor Dimitrov and enjoyed a long-term relationship with rapper Common, who admitted he was ready to marry her.

Like good wine, Williams improves with age. Her glowing CV of accomplishments means that she has surpassed tennis icons Martina Navratilova and Billie Jean King.

The question is will she be able to reassert her superiority and finally get her revenge against the youngster who threatened her crown.

Muguruza is so determined to win that the superstitious Spaniard has banned her parents from the court.

"She [Williams] knows that I can win against her, that I'm not afraid. I don't think she's really used to this, Serena doesn't lose many matches in the year. But she's world No 1 for something. It's going to be my hardest challenge."
