That is so stupid to compare Federer to Serena. Why do they then move Roger to WTA and Serena to ATP ? Then will see how many GS Fed would win and how many Serena will have. Why do they do not compare Fed to Steffi Graf ? What do you think if Fed plays SF at FO vs Eranni BO3 sets? Who is going to win ? Maybe Serena is better than Sampras ? It is really stupid !!!
Any of the guys would probably lose to Errani. They'd be too busy cracking up with laughter to remember to return the serve..
