The split may come as a surprise to some, however, as Sharapova gushed about her longtime lover in an interview.
Even more importantly, Sharapova will be facing a reigning Grand Slam champion, Muguruza having won the French Open earlier this year.
Despite the triumphant reaction of Sharapova and some of those around her following the reduction of her suspension from two years to 15 months by the Court of Arbitration for Sport earlier this month, the inescapable fact is that the Russian is still banned because she tested positive for what the World Anti-Doping Agency considers to be a performance-enhancing drug.
Even if you take at face value Sharapova’s assertion that she had been taking Meldonium (under its trade name of Mildronate) for genuine health reasons since 2006 and that the tennis authorities had failed to give sufficient warning that the drug was being placed on the banned list from the start of this year, an athlete remains responsible for any substance entering their body.
She's better off serving some love to a fellow Russian star, who's closer to her age and reaching his peak at the same time she is.
These two winter sports stars would go together better than ice and snow.
