She's one of the favourites to win the 2013 Mutua Madrid Open, and here are five reasons why Serena Williams can win the title in the Spanish capital...
1. She dominated the field last year
Dropping just one set en route to the title, Serena pretty much thrashed everyone that she came up against. Yes, the tournament was played on the slippery blue clay last season, but Serena's superiority last year is worth taking into account. When she lost the first set in her third round meeting with Caroline Wozniacki she bit back to take the match confidently. In the semi-finals when she was forced into a first set tie-breaker, she went on to bagel Lucie Hradecka to clinch victory. With the exception of these two sets, she didn't lose more than 3 games in any other set, and this record included demolition jobs on Maria Sharapova and Victoria Azarenka.
2. She was outstanding on clay last season
Serena only lost one match on clay last season, picking up titles in Charleston and Madrid. Her first round loss at Roland Garros can't really be considered as anything other than a one-off. Had she not had an off-day against Virginie Razzano, there's a fair chance that Williams would be entering the 2013 French Open as the defending champ.
3. She's in great form
There have been one or two surprise defeats for Serena this year, but even taking that into account she's rightfully placed at the top of the rankings. She's won 3 WTA titles already this season, reached the final in Doha, and reached the quarter-finals of the Australian Open. Some people read a bit too much into her defeat against Sloane Stephens in Melbourne, but Serena was clearly injured at the time and to add to this can't be expected to win every match that she plays.
4. The hunger is back
There were times in the careers of the Williams sisters where it looked like off-court commitments were their top priority. Now, entering the latter stages of their careers, both seem to be relishing their time in competitive action a lot more. Serena in particular has stepped up her commitment, taking part in more tournaments and pressing home her claim to being the WTA's greatest player of all-time.
5. She's fully fit
Serena endured a few injury problems earlier in the season, but she's given herself plenty of time to regroup and get ready before heading to the Magic Box. She was in devastating form in Fed Cup action last week and seems ready to take on anyone.
